=== 1977–1980 ===
The Mariners' original colors were blue and gold, the color scheme previously used by the Seattle Pilots and its successor Milwaukee Brewers. For the first four seasons, they wore white pullover jerseys at home with the team name in front and numbers on the left chest. The "M" in "Mariners" was shaped to resemble a [[trident]]. On the road, they wore baby blue pullover jerseys with the city name in front and numbers on the left chest. The lettering colors were blue with gold trim, though in the 1977 season the trim on the road jersey was white and the "Seattle" wordmark appeared smaller. The trident logo was added to the left sleeve prior to the 1979 season.

The cap was all-blue and featured the gold trident logo with white trim.

===1981–1986===
The Mariners made some subtle changes to the uniform in 1981. The trident logo was replaced by blue and gold racing stripes on the shoulders, and the lettering received an extra blue outline. The number font also changed from rounded to block style. In 1985, the road jersey color was changed to grey.

The cap logo also featured a slight update of the trident logo, changing its color to blue, along with additional outlines and a white star background, a logo first used for the 1979 All-Star Game.[[File:1987 Mother's Cookies - Scott Bankhead.jpg|thumb|upright|[[Scott Bankhead]] in the uniform design from 1987 to 1992]]

=== 1987–1992 ===
In 1987, the Mariners changed its uniform style to traditional buttoned tops and belted pants. Both uniforms incorporated blue piping and a block "Mariners" wordmark in blue with gold and blue outlines. The numbers remained blue, but eliminated the trim outlines.

The cap logo was changed to a gold "S."

===1993–present===
The Mariners donned their current uniforms in {{mlby|1993}}. The white home uniform originally featured "Mariners" in navy with trim in a dark shade of cyan called "Northwest Green" and featured the "compass rose" logo atop the "M."<ref>{{Cite book |url=https://img.mlbstatic.com/mlb-images/image/upload/fl_attachment/mlb/mdp226e3cw9r2wo37o0t.pdf |title=Seattle Mariners 2021 Information Guide |publisher=Seattle Mariners |year=2021 |pages=189}}</ref> The grey road uniform originally featured "Seattle" in navy with Northwest Green and white trim; in 2001, the compass rose logo was added in the middle of the "S." In 2015, a silver inline was added to the wordmark of both uniforms, which was also applied to the block letters and numbers. The primary logo is applied to the left sleeve.<ref name="Mariners2015Uniforms">{{Cite web |last=Novak |first=Paul |date=January 23, 2015 |title=Seattle Mariners Unveil New Uniforms |url=https://emeraldcityswagger.com/2015/01/23/seattle-mariners-unveil-new-uniforms/ |access-date=February 11, 2018 |website=emeraldcityswagger.com |publisher=Open Publishing}}</ref>

From 1997 to 2000, the Mariners also wore sleeveless versions of their primary uniforms, accompanied with a navy undershirt.

The Mariners have also worn Northwest Green alternate uniforms at different points in their history. The original version was unveiled in 1994 and had "Mariners" in silver with navy and white trim. The next season, the white trim was removed<ref>{{Cite web |title=Seattle Mariners Uniform - Alternate Uniform - American League (AL) - Chris Creamer's Sports Logos Page |url=https://www.sportslogos.net/logos/view/k8ubhh09gpbew6c3ohqenfxge/Seattle_Mariners/1995/Alternate_Uniform |access-date=2024-10-08 |website=SportsLogos.Net}}</ref> to improve visibility. The Mariners did not wear green uniforms from 1997 to 2010, after which it became a regular part of their uniform rotation. Formerly worn on Friday home games, the Northwest Green alternates are currently worn on select Saturday home games and on road games in which the home team wears either navy or black uniforms.<ref name=adam/><ref>{{Cite web |last=Divish |first=Ryan |author-link=Ryan Divish |date=October 20, 2010 |title=Mariners going green...with their jerseys |url=http://blog.thenewstribune.com/mariners/2010/10/20/mariners-going-green-with-their-jerseys/ |url-status=dead |archive-url=https://web.archive.org/web/20150201021742/http://blog.thenewstribune.com/mariners/2010/10/20/mariners-going-green-with-their-jerseys/ |archive-date=February 1, 2015 |access-date=January 31, 2015 |website=[[The News Tribune]]}}</ref>

The navy alternate uniform originally replaced the Northwest Green alternate in 1997 and featured the team name in silver with Northwest Green and navy trim. In 1999, the alternates were updated to feature the city name with the "S" behind the compass rose logo and silver piping; this became their road alternate the following season after a corresponding home navy alternate was introduced. In 2003, the silver piping was removed and the letter and number fonts were changed to match the wordmark. In 2012, after the Northwest Green home alternates were brought back, the navy uniforms were tweaked anew, this time with the city name in front and stylized serifed letters instead of the normal block letters. In 2024, the names were changed to block lettering. It is now worn on most road games, though they have also donned them at home on occasion.

A navy blue cap that features a ball and compass rose "S" logo is paired with the home white, road gray, and navy blue jerseys. A variation of this cap with a Northwest Green brim is worn with the home alternate jersey. In 1994, the Mariners also wore Northwest Green caps with navy brims, and in 1997 the team wore a navy cap with grey brims.

In January 2015, the team announced a new alternate uniform to be worn for Sunday home games. This cream-colored "fauxback" uniform features the current logo and lettering style in a royal blue and gold color scheme, a throwback to the original team colors. Unlike the rest of the uniform set, the back of the jersey does not display the player name.<ref name="adam">{{Cite web |last=Lewis |first=Adam |date=January 23, 2015 |title=Mariners Unveil New Alternate Home Uniforms |url=http://sportspressnw.com/2197039/2015/mariners-unveil-new-alternate-home-uniforms |access-date=January 31, 2015 |website=Sports Press NW}}</ref><ref name="NewSundayAlternate" /> The cap features the current cap logo in the throwback colors.<ref name="NewSundayAlternate" /><ref>{{Cite news |last=Divish |first=Ryan |author-link=Ryan Divish |date=January 23, 2015 |title=Mariners debut new alternate uniform for Sunday home games |url=http://blogs.seattletimes.com/mariners/2015/01/23/mariners-debut-new-home-alternate-uniform-for-sunday-games/ |url-status=dead |archive-url=https://web.archive.org/web/20150201001615/http://blogs.seattletimes.com/mariners/2015/01/23/mariners-debut-new-home-alternate-uniform-for-sunday-games/ |archive-date=February 1, 2015 |access-date=January 31, 2015 |work=[[The Seattle Times]]}}</ref>

In January 2019, the Mariners announced a new home and away uniform to be worn during [[spring training]]. The jersey has a design similar to their home white jerseys but features a powder blue throwback to the team colors during the 1980s. The cap has the usual navy blue color, but with a logo that features the signature [[compass rose]] and with a large M in the center.

For the [[2023 Major League Baseball season|2023 season]], MLB and Nike have instituted a "four plus one" model for team uniforms, consisting of a home uniform, away uniform, two alternate uniforms, and a [[City Connect]] uniform featuring "color schemes and logos that pay homage to a team’s city."<ref name="Nike4plus1uniforms">{{Cite news |date=January 16, 2023 |title=Cardinals Warm-up Live: Cardinals will wear City Connect uniforms in 2024 |url=https://www.stltoday.com/sports/baseball/professional/cardinal-beat/cardinals-warm-up-live-cardinals-will-wear-city-connect-uniforms-in-2024/article_66df167c-d6bc-54be-b859-c0301658b2c6.html |archive-url=https://web.archive.org/web/20230116174330/https://www.stltoday.com/sports/baseball/professional/cardinal-beat/cardinals-warm-up-live-cardinals-will-wear-city-connect-uniforms-in-2024/article_66df167c-d6bc-54be-b859-c0301658b2c6.html |archive-date=January 16, 2023 |access-date=January 28, 2023 |work=[[St. Louis Post-Dispatch]]}}</ref> The Mariners confirmed that they will replace the gray jerseys with the navy blue jerseys as their standard away uniforms for the 2023 season.<ref name="Mariners2023uniforms">{{Cite web |last=Creamer |first=Chris |date=January 27, 2023 |title=Seattle Mariners Drop Grey Unis for 2023, will wear Navy Blue for Road Games |url=https://news.sportslogos.net/2023/01/27/seattle-mariners-drop-grey-unis-for-2023-will-wear-navy-blue-for-road-games/baseball/ |archive-url=https://web.archive.org/web/20230128040431/https://news.sportslogos.net/2023/01/27/seattle-mariners-drop-grey-unis-for-2023-will-wear-navy-blue-for-road-games/baseball/ |archive-date=January 28, 2023 |access-date=January 28, 2023 |website=[[SportsLogos.net]]}}</ref><ref name="Mariners2023uniformsST">{{Cite news |last=Divish |first=Ryan |author-link=Ryan Divish |date=January 27, 2023 |title=Mariners ditching gray road jerseys because of new MLB rules |url=https://www.seattletimes.com/sports/mariners/mariners-ditching-gray-road-jerseys-because-of-new-mlb-rules/ |archive-url=https://web.archive.org/web/20230129020558/https://www.seattletimes.com/sports/mariners/mariners-ditching-gray-road-jerseys-because-of-new-mlb-rules/ |archive-date=January 29, 2023 |access-date=January 28, 2023 |work=[[Seattle Times]]}}</ref> The team will also stop using the powder blue jerseys during spring training.<ref name="Mariners2023uniforms" /> The choice to remove the gray and powder blue jerseys was based on feedback from players and fans, according to Kevin Martinez, the Mariners senior vice president of marketing and communications.<ref name="Mariners2023uniformsST" />

The Mariners' City Connect uniform is a visual nod to Seattle's baseball history. The jersey includes a sleeve patch featuring [[Mount Rainier]] and the letters "PNW," an acronym for [[Pacific Northwest]]. The jersey also includes the inaugural colors of the team and the word "Seattle" across the chest lettering reminiscent of the [[Seattle Pilots]]. The jersey is paired with a cap that has new design of the trident logo and black pants. This uniform is primarily worn during Friday home games.<ref>{{Cite web |title=Spirit, colors of Pacific Northwest come alive in Mariners' City Connect unis |url=https://www.mlb.com/news/mariners-city-connect-uniforms-unveiled |access-date=April 28, 2023 |website=MLB.com |language=en}}</ref> The team wore the City Connect uniform more frequently in 2024, since they won most of their games in the alternates.<ref>{{Cite web |date=2024-09-15 |title=Seattle Mariners Wearing Fan-Favorite Threads for Series Final Against Texas Rangers |url=https://www.si.com/mlb/mariners/news/seattle-mariners-will-wear-fan-favorite-and-lucky-citty-connect-uniforms-for-series-finale-against-texas-rangers-on-sunday |access-date=2025-03-06 |website=Seattle Mariners On SI |language=en-US}}</ref> In the upcoming 2025 season, the Mariners will once again partner with Nintendo of America, with the Nintendo “racetrack” logo on the sleeve of the home game jersey and the logo of the [[Nintendo Switch 2]] on the sleeve of the away game jersey.<ref>{{Cite web |date=2025-03-20 |title=The Seattle Mariners are getting Nintendo patches on their jerseys |url=https://www.espn.com/gaming/story/_/id/44330467/seattle-mariners-nintendo-jerseys |access-date=2025-03-20 |website=ESPN.com |language=en}}</ref>
