[[File:WalesRugbyRegions.png|thumb|left|150px|A diagram showing the development pathways managed by Wales' professional clubs]]
In 2003, the WRU elected to reduce the top tier of Welsh professional rugby from nine clubs into five regions during the [[introduction of regional rugby union teams in Wales]], attempting to mirror the successful formats in Ireland, South Africa, Australia and New Zealand.

Initially, it was planned to have a region playing at Stradey Park, with players coming from [[Llanelli RFC|Llanelli]], [[Swansea RFC|Swansea]] and [[Neath RFC|Neath]].<ref>{{cite news |title=WRU drops provincial bombshell |url=http://news.bbc.co.uk/sport1/hi/rugby_union/celtic/2547339.stm |website=BBC Sport |date=20 February 2003 |access-date=5 December 2006 }}</ref> This was then modified to have Llanelli and Swansea merging, while Neath joined with [[Bridgend Ravens|Bridgend]]. Llanelli were opposed to both plans and requested standalone status.<ref>{{cite news |title=Moffett scraps northern expansion |url=http://news.bbc.co.uk/sport1/hi/rugby_union/celtic/2639325.stm |website=BBC Sport |date=8 January 2003 |access-date=5 December 2006 }}</ref> Eventually, Llanelli and [[Cardiff RFC|Cardiff]] were allowed to remain independent.<ref>{{cite news |title=Layman's guide to Welsh rugby's crisis |url=http://news.bbc.co.uk/sport1/hi/rugby_union/welsh/2845137.stm |website=BBC Sport |date=12 March 2003 |access-date=5 December 2006 }}</ref> The Llanelli Scarlets brand was officially launched on 7 July 2003.<ref>{{cite news |title=Scarlets launch regional vision |url=http://news.bbc.co.uk/sport1/hi/rugby_union/welsh/3051870.stm |website=BBC Sport |date=7 July 2003 |access-date=5 December 2006 }}</ref>

Despite always having been a 100% owned Llanelli RFC subsidiary, the Scarlets were originally conceived as representing the whole of West and North Wales. In the early seasons of regional rugby, the Scarlets played a small number of games at the Racecourse Ground in Wrexham. While nominally continuing to be the regional franchisee for North Wales, the Scarlets presence there has diminished.<ref>{{cite news |title=Scarlets staying put |url=https://www.walesonline.co.uk/sport/rugby/rugby-news/scarlets-staying-put-2332279 |work=Wales Online |date=8 June 2006 |access-date=29 March 2021 }}</ref> As of 2018, the Scarlets consider their region to represent the three counties of [[Carmarthenshire]], [[Ceredigion]] and [[Pembrokeshire]].<ref>{{Cite news |url=https://www.bbc.co.uk/news/uk-wales-45172501 |title=Scarlets away kit to be inspired by region's history |date=14 August 2018 |website=BBC News |access-date=14 December 2018}}</ref>

===2003–2014===
{{For|history of pre-2003 Llanelli rugby|Llanelli RFC}}

====2003–04 season====
Largely drawn from the Llanelli RFC side that won the Welsh Cup the preceding year, the Scarlets carried that success forward into their inaugural season. They reached the last eight of the [[2003–04 Heineken Cup]] and finished the [[Pro14|Celtic League]] season as champions by four points over [[Ulster Rugby|Ulster]]. In the Heineken Cup, the Scarlets were drawn in Pool 4 along with [[Northampton Saints]], [[SU Agen Lot-et-Garonne|Agen]] and [[Border Reivers (rugby)|Borders]]. The Scarlets won five of their six matches, losing only to Agen, and finished top of their pool before losing to French club [[Biarritz Olympique|Biarritz]] 27–10 in the quarter-finals.

====2004–05 season====
[[File:Magners League Scarlets Vs. Glasgow.jpg|thumb|150px|Scarlets players during a league match against [[Glasgow Warriors]] in 2006]]
The following season, however, was less successful. Plagued by injuries and retirements, as well as the departure of influential fly-half [[Stephen Jones (rugby union)|Stephen Jones]] to [[ASM Clermont Auvergne|Clermont]], the Scarlets finished a disappointing fifth in the league. They were even less successful in the Heineken Cup, winning just two of their six pool games to finish third behind Northampton and [[Stade Toulousain|Toulouse]]. The salvation of their season came in reaching the final of the [[Celtic Cup (rugby union)|Celtic Cup]], which they lost 26–17 to [[Munster Rugby|Munster]].

====2005–06 season====
The Scarlets again failed to qualify from their Heineken Cup group in 2005–06 and finished sixth in the Celtic League. They did, however, find more success in the newly restructured [[Anglo-Welsh Cup]]. After finishing at the top of their pool, they defeated [[Bath Rugby|Bath]] by one point in the semi-finals to reach the final against [[Wasps RFC|London Wasps]] at [[Twickenham Stadium|Twickenham]]; missing several international players, they lost 26–10. In the Heineken Cup, it was a similar story to the previous season, with the Scarlets winning two of their six fixtures to finish third in the pool again, behind Toulouse and Wasps. Despite finishing sixth in the Celtic League, the team qualified for the Heineken Cup for the 2006–07 season as the second-best-placed Welsh team in the league. They also re-signed Stephen Jones, and full-back Barry Davies extended his contract to stay with the Scarlets. The Scarlets' Director of Rugby, [[Gareth Jenkins]], had been appointed as Wales' national team coach, having been with the region since its inception. [[Phil Davies (rugby union)|Phil Davies]], then coach of [[Leeds Tykes]], replaced Jenkins at the Scarlets.<ref>{{cite news |title=Scarlets unveil Davies as coach |url=http://news.bbc.co.uk/sport1/hi/rugby_union/welsh/4790797.stm |website=BBC Sport |date=14 August 2006 |access-date=5 December 2006 }}</ref>

====2006–07 season====
At the first home game of the 2006–07 season, an information sheet was handed out to supporters with details of the club's financial situation. There was opposition by local residents to plans by the Scarlets to move to a new stadium and sell their current ground for housing development. The information sheet stated that, due to delays caused by the opposition and benefactors pulling out of the club, it was "extremely unlikely that [the Llanelli Scarlets] could survive to the end of the present season unless other financial assistance is found", which would result in "the loss, probably for all time, of professional rugby in West Wales." Local residents believed, however, that the infrastructure, such as roads and schools, will not cope with 450 new houses being built on the site. On 28 November 2006, the regions secured investment from Tim Griffiths, a London-based businessman.<ref>{{cite news |title=Scarlets 'saved' by new investor |url=http://news.bbc.co.uk/sport1/hi/rugby_union/my_club/llanelli_scarlets/6191096.stm |website=BBC Sport |date=28 November 2006 |access-date=5 December 2006 }}</ref>

In the [[2006–07 Heineken Cup]], the Scarlets recorded one of the most famous victories in their brief history as a region, defeating Toulouse 41–34 away, despite twice trailing by 21 points. This was an unexpected victory, despite the Scarlets having won their first three games of the 2006–07 competition. They later secured their place in the Heineken Cup quarter-final with a convincing 35–11 win over Ulster at [[Ravenhill Stadium|Ravenhill]]. The Scarlets went on to become only the fifth team in the history of the competition to win all their pool matches. They beat current holders Munster 24–15 at [[Stradey Park]] in the quarter-finals, but were beaten 33–17 in the semis by a strong [[Leicester Tigers]] side, putting an end to their hopes of making it 'third time lucky' in Heineken Cup semi-finals.

====2007–08 season====
On 30 April 2008, Phil Davies was replaced by [[Nigel Davies (rugby union)|Nigel Davies]] after a sixth-place finish in the Celtic League and an end of season slump.<ref>{{cite web |date=14 May 2008 |title=Scarlets turn to Nigel Davies |url=https://www.planetrugby.com/scarlets-turn-to-nigel-davies |access-date=12 October 2022}}</ref>

====2008–09 season====
The Scarlets moved from Stradey Park at the end of November 2008 to a new ground at Pemberton called [[Parc y Scarlets]]. The final Scarlets match played at Stradey Park was on 24 October 2008, against [[Bristol Rugby|Bristol]] in the group stage of the Anglo-Welsh Cup. The Scarlets won 27–0 in front of a capacity crowd, which included former Llanelli captains such as [[Delme Thomas]] and [[Phil Bennett]].<ref>{{cite news |title=Scarlets win on Stradey farewell |url=http://news.bbc.co.uk/sport1/hi/rugby_union/my_club/llanelli_scarlets/7685886.stm |website=BBC Sport |date=24 October 2008 |access-date=18 November 2008 }}</ref>

The Scarlets' first match at their new home was an 18–16 Celtic League defeat to Munster on 28 November 2008.<ref>{{cite news |title=Scarlets 16–18 Munster |url=http://news.bbc.co.uk/sport1/hi/rugby_union/welsh/7750812.stm |website=BBC Sport |date=28 November 2008 |access-date=26 December 2008 }}</ref> Their first Heineken Cup match at Parc y Scarlets was held on 12 December against Ulster and finished in a 16–16 draw.<ref>{{cite news |title=Scarlets 16–16 Ulster |url=http://news.bbc.co.uk/sport1/hi/rugby_union/7777554.stm |website=BBC Sport |date=12 December 2008 |access-date=26 December 2008 |first=Gareth |last=Roberts}}</ref> Both matches were held with reduced capacity, as law requires that a new stadium hold three events at reduced capacity before it is authorised for its full capacity. The official opening ceremony was on 31 January 2009, when the Scarlets faced the [[Barbarian F.C.|Barbarians]].

====2011–12 season====
[[File:Scarlets lineout.JPG|thumb|150px|Scarlets players contest a [[Line-out (rugby union)|line-out]] in a match against [[Benetton Rugby|Benetton Treviso]] in 2013]]
During the 2011–12 season, the Scarlets were unable to progress to the knockout rounds of the Heineken Cup, but placing second in their pool earned them an automatic drop-down spot in the quarter-finals of the Challenge Cup. They lost the resulting fixture against Brive 15–12, despite scoring the only try of the match through Liam Williams.<ref>{{Cite news |date=8 April 2012|title=Scarlets exit Amlin Challenge Cup with quarter-final defeat at Brive |work=The Guardian |url=https://www.theguardian.com/sport/2012/apr/08/brive-scarlets-amlin-challenge-cup |access-date=2 April 2023 |issn=0261-3077}}</ref>

Nigel Davies departed the club at the conclusion of the 2011–12 season, and was replaced by defence coach and longtime Scarlets player, [[Simon Easterby]].<ref>{{cite news |url=https://www.bbc.co.uk/sport/rugby-union/18304544 |title=Simon Easterby is appointed the new Scarlets coach |website=BBC Sport |date=2 June 2012 |access-date=12 October 2012}}</ref>

===2014–2019: Wayne Pivac years===
====2014–15 season====
In May 2014, it was confirmed that the four Welsh regions would compete in the annual Premiership Sevens Series after a three-year deal was agreed with [[BT Sport]].<ref>{{cite news |title=Welsh regions included in Premiership Sevens Series |url=https://www.bbc.co.uk/sport/0/rugby-union/27502315 |website=BBC Sport |date=21 May 2014 |access-date=23 March 2015 }}</ref>

After the 2013–14 season, the Scarlets had numerous changes in coaching staff. Forwards coach [[Danny Wilson (rugby union)|Danny Wilson]] departed for Bristol, while [[Byron Hayward]] joined as a defense coach. [[Wayne Pivac]] was hired as an assistant coach, but selected as head coach when Simon Easterby left the position to become forwards coach with [[Ireland national rugby union team|Ireland]].<ref>{{cite news |url=https://www.walesonline.co.uk/sport/rugby/rugby-news/scarlets-announce-wayne-pivac-take-7602454 |title=Scarlets announce Wayne Pivac will take over as head coach as Simon Easterby pursues new role with Irish national team |website=Wales Online |date=12 August 2014 |access-date=12 October 2022 }}</ref>

Under Pivac, the Scarlets' performances did not immediately turn around. Centre [[Jonathan Davies (rugby union, born 1988)|Jonathan Davies]] left for Clermont ahead of the 2014–15 season, but [[Hadleigh Parkes]] was signed from Auckland, and reunited with former coach Pivac. Mid-table finishes continued for the next two seasons. [[Mark Jones (rugby union, born 1979)|Mark Jones]] departed in 2015, replaced by long time Scarlets fly-half and London Wasps attack coach Stephen Jones.<ref>{{cite web|url=https://www.wru.wales/2015/01/stephen-jones-returning-to-scarlets-as-mark-jones-moves-on/|title=Stephen Jones returning to Scarlets as Mark Jones moves on|date=12 January 2015|access-date=14 October 2022|publisher=Welsh Rugby Union}}</ref>

====2016–17 season====
Ahead of 2016, [[Tadhg Beirne]] joined the side. The Irish forward arrived from [[Leinster Rugby|Leinster]], and capable of playing at lock and in the back row, proved to be an influential player in the pack. Recruitment was further bolstered with [[Crusaders (rugby union)|Crusaders]] back [[Johnny McNicholl]] and the return of Jonathan Davies from France. Fly-half [[Rhys Patchell]] was signed from [[Cardiff Rugby|Cardiff Blues]], with [[Steven Shingler]] moving in the opposite direction. The season started poorly, with the Scarlets losing their first three matches. Improvements throughout the season saw the Scarlets finish in third place in the table, qualifying for the play-offs. The Scarlets beat Leinster away at the RDS Stadium, 27–15, despite winger [[Steff Evans]] being sent off in the first half.<ref>{{cite web|url=https://www.allwalessport.co.uk/rugby-union.aspx?cid=10673|title=Pro12: Leinster 15-27 Scarlets|website=BBC Sport|date=19 May 2017|access-date=October 14, 2022}}</ref> The Scarlets beat Munster in the final with an emphatic 46–22 win.<ref>{{cite web|url=https://www.bbc.co.uk/sport/rugby-union/40056082|title=Pro12 final: Munster 22-46 Scarlets|website=BBC Sport|date=27 May 2017|access-date=14 October 2022}}</ref> This was the Scarlets second title, their first having come in 2004 during the first Celtic League season.

====2017–18 season====
The Scarlets looked to maintain their title the following season in the inaugural Pro14 tournament. [[Leigh Halfpenny]] joined from [[RC Toulonnais|Toulon]], replacing outgoing fullback [[Liam Williams (rugby union)|Liam Williams]]. They topped their pool in the [[2017–18 European Rugby Champions Cup|Champions Cup]], and defeated [[Stade Rochelais|La Rochelle]] 29–17 in the quarter-final.<ref>{{cite web|url=https://www.skysports.com/rugby-union/scarlets-vs-la-rochelle/86387|title=Scarlets 29-17 La Rochelle: Wayne Pivac's men book Champions Cup semi-final spot|date=30 March 2018|access-date=14 October 2022|website=Sky Sports}}</ref> The Scarlets fell short of the final, losing to eventual winners Leinster in their semi-final.<ref>{{cite web|url=https://www.bbc.co.uk/sport/rugby-union/43795196|title=European Champions Cup: Leinster 38-16 Scarlets|date=21 April 2018|access-date=14 October 2022|website=BBC Sport}}</ref>

They again reached the final in the league, having defeated the [[Cheetahs (rugby union)|Cheetahs]] and [[Glasgow Warriors]] in the knock-out rounds, but came up short against Leinster, losing 40–32 in the [[2018 Pro14 Grand Final|final]] despite a late flurry of tries and a hat-trick from Johnny McNicholl.<ref>{{cite web|url=https://www.bbc.co.uk/sport/rugby-union/44252575|title=Pro14 final: Leinster 40-32 Scarlets|date=26 May 2018|access-date=14 October 2022|website=BBC Sport}}</ref>

====2018–19 season====
Wayne Pivac was announced as [[Warren Gatland]]'s successor as Wales coach after the 2019 Rugby World Cup.<ref>{{cite news|title=Wayne Pivac to succeed Gatland as new Wales coach after the World Cup|url=https://www.theguardian.com/sport/2018/jul/09/wayne-pivac-to-succeed-gatland-as-new-wales-rugby-union-coach-after-the-world-cup|website=The Guardian|date=9 July 2018|access-date=14 October 2022}}</ref> With him left Stephen Jones and Byron Hayward, who joined Pivac on the Wales coaching staff.

Crusaders assistant coach [[Brad Mooar]] was announced as the next head coach in December 2018.<ref>{{cite web|url=https://www.itv.com/news/wales/2018-12-03/brad-mooar-to-replace-pivac-as-scarlets-head-coach|title=Brad Mooar to replace Pivac as Scarlets head coach|date=3 December 2018|access-date=14 October 2022|website=ITV News}}</ref>

====Project Reset====
{{main|Project Reset (Welsh Rugby Union reform)}}
In 2018, the Welsh Rugby Union sought to reform club rugby in Wales.<ref>{{Cite web |last=Thomas |first=Simon |date=11 July 2018 |title=Project Reset uncovered: confidential new Welsh rugby deal changes everything |url=https://www.walesonline.co.uk/sport/rugby/rugby-news/project-reset-uncovered-confidential-new-14896396 |access-date=2 April 2023 |website=WalesOnline }}</ref> Salaries had increased as they worked to entice Welsh players abroad to return, and they aimed to streamline costs with a banding system. The Professional Rugby Board (PRB) was created between the WRU and clubs to attempt to identify a sustainable path forward. The PRB evaluated numerous options including mergers and relocations of clubs, and by early 2019 felt the preferable option was to merge the Scarlets with west Wales rivals the [[Ospreys (rugby union)|Ospreys]]; the Swansea club having made a made an approach to the Scarlets in late 2018.<ref>{{Cite news |title=Scarlets-Ospreys merger talks to be held |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/47443612 |access-date=2 April 2023}}</ref> This was not the first time a west Wales super club had been mooted; during the 2003 formation of regional rugby, a combination of the Llanelli, Swansea, and Neath forming a unified club was initially proposed.<ref>{{Cite news |date=20 February 2003 |title=WRU drops provincial bombshell |url=http://news.bbc.co.uk/sport2/hi/rugby_union/celtic/2547339.stm |access-date=2 April 2023}}</ref> The new combined club would play league matches at Parc y Scarlets, with European fixtures at the Ospreys' [[Liberty Stadium]]. Shortly after the proposal was revealed, Scarlets ownership indicated the merger was "off the table", with Ospreys chairman Mike James resigning, and the club formation ultimately remaining unchanged.<ref>{{Cite news |title=Scarlets-Ospreys merger 'off the table' |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/47461662 |access-date=2 April 2023}}</ref>

===2019–2021: Coaching changes===
====2019–20 season====
New coach Brad Mooar started the 2019 season well, winning five out of the first six matches, but left before settling in, having been selected by new All Blacks coach [[Ian Foster (rugby union)|Ian Foster]] to join his staff as assistant coach. The Scarlets and the [[New Zealand Rugby Union]] agreed to a release for Mooar, and his assistant coach [[Glenn Delaney]] was named as his successor.<ref>{{cite web|url=https://www.bbc.co.uk/sport/rugby-union/51351287|title=Scarlets: Glenn Delaney promoted to head coach role|website=BBC Sport|date=6 February 2020|access-date=14 October 2022}}</ref>

====2020–21 season====
Former Scarlets [[Dwayne Peel]] was announced as head coach for the forthcoming season, with Delaney moving to a Director of Rugby role.<ref>{{Cite news |title=Delaney excited for Peel's Scarlets return |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/56834022 |access-date=20 December 2022}}</ref> Peel was at the time contracted to join Cardiff Blues for the following season, as an assistant coach responsible for attack.<ref>{{Cite news |title=Peel to join Blues staff from Ulster |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/55226951 |access-date=2 April 2023}}</ref> Following the dismissal of Blues head coach [[John Mulvihill (rugby union)|John Mulvihill]], former coach Dai Young made a return to the club initially as interim head coach and finally Director of Rugby.<ref>{{Cite news |title=Young back at Blues as Mulvihill leaves |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/55580051 |access-date=2 April 2023}}</ref> Due to this new coaching structure, the Scarlets and Blues came to an agreement allowing for Peel to no longer join Cardiff as an assistant coach, and instead join the Scarlets as head coach.<ref>{{Cite news |title=Scarlets appoint Peel as head coach |work=BBC Sport |url=https://www.bbc.com/sport/rugby-union/56803887 |access-date=2 April 2023 }}</ref>

=== 2021–present: Dwayne Peel era ===
====2021–22 season====
Ahead of the [[2021–22 United Rugby Championship]], Leinster skills coach Hugh Hogan was brought in as defence coach.<ref>{{Cite news |title=Hogan signs at Scarlets as Whiffin exits |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/57930167 |access-date=20 December 2022}}</ref> The Scarlets finished in 10th place, and narrowly missed out on winning the newly created URC Welsh Shield.

====2022–23 season====
Few signings were made prior to the [[2022–23 United Rugby Championship]] season, with All Blacks utility forward [[Vaea Fifita]] the headline acquisition, while Liam Williams departed for Cardiff following his second spell with the club. Longtime prop [[Rob Evans (rugby union)|Rob Evans]] followed [[Steffan Hughes (rugby union)|Steffan Hughes]], and former Dragon [[Angus O'Brien]] to the [[Dragons RFC|Dragons]], along with backs coach Dai Flanagan, who was named as their new head coach.<ref>{{Cite news |title=Flanagan named new Dragons head coach |work=BBC Sport |url=https://www.bbc.co.uk/sport/rugby-union/61877976 |access-date=20 December 2022}}</ref>

The Scarlets took their name from the nickname of Llanelli RFC, their main feeder club. Llanelli have played in red since 1884 when they played a game against a touring Ireland side.<ref>{{cite web |url=http://www.llanellirfc.co.uk/125-2 |title=Llanelli RFC - History |website=Llanelli RFC |access-date=4 October 2022}}</ref> This close link with Llanelli RFC has also led to the Scarlets adopting the [[Scarlet (color)|scarlet red]] colour for their primary jerseys, with their secondary colours generally being blue.

The region was originally named the Llanelli Scarlets, but was renamed at the start of the 2008–09 rugby season to more accurately represent the area covered by the region.<ref name="Scarlets drop Llanelli from name"/>
