During the 1980s, Stena acquired three other ferry companies.

* 1981, Sessan Line, Stena's biggest competitor on Sweden–Denmark routes, was acquired and incorporated into Stena Line.<ref>{{cite web|url=http://www.faktaomfartyg.se/sessanlinjen.htm |publisher=Fakta om Fartyg |title=Sessan Linjen |language=sv |access-date=21 September 2007 |archive-url=https://archive.today/20120801081056/http://www.faktaomfartyg.nu/sessanlinjen.htm |archive-date=1 August 2012 |url-status=dead}}</ref> This included Sessan's two large newbuilds, ''Kronprinsessan Victoria'' and {{MS|Prinsessan Birgitta||2}}, which became the largest ships operated by Stena by that date.{{fact|date=October 2024}}
* 1983, Stena acquired Varberg-Grenå Linjen, and two years later also the right to that company's former name, [[Lion Ferry]]. Lion Ferry continued as a separate marketing company until 1997, when it was incorporated into Stena Line.<ref>{{cite web|url=http://www.faktaomfartyg.se/lion_ferry.htm |publisher=Fakta om Fartyg |title=Lion Ferry |language=sv |access-date=21 September 2007 |archive-url=https://archive.today/20120729150759/http://www.faktaomfartyg.nu/lion_ferry.htm |archive-date=29 July 2012 |url-status=dead}}</ref> 
* 1989, Stena acquired yet another ferry company, [[Stoomvaart Maatschappij Zeeland|Stoomvaart Maatschappij Zeeland (SMZ)]] (''which at the time traded under the name Crown Line''). SMZ's [[Hook of Holland]]–[[Harwich International Port|Harwich]] route then became a part of Stena Line.<ref>{{cite web|url=http://www.faktaomfartyg.se/stoomvaart_maatschappij_zeeland.htm |publisher=Fakta om Fartyg |title=Stoomvaart Maatschappij Zeeland |language=sv |access-date=21 September 2007 |archive-url=https://archive.today/20120731163420/http://www.faktaomfartyg.nu/stoomvaart_maatschappij_zeeland.htm |archive-date=31 July 2012 |url-status=dead}}</ref>
