Marcus Fraser, born on 23 June 1994 (age 32), is a Scottish central defender whose senior career began at Celtic but has been shaped much more firmly by what came later. He came through at Celtic as a trainee, part of the club’s system before his first-team career was properly made elsewhere.
He left Celtic in January 2015 for Ross County, a practical move that gave him the senior football he needed. The 2014–15 league season was his most productive in front of goal, with one goal in 16 appearances, though goals have never been the point of his game.
After Ross County, Fraser found his longer-term home at St Mirren. Across seven seasons he has made 214 league appearances and scored four league goals, a fair measure of how heavily his career has come to rest in Paisley. He has been primarily used as a central defender, steady enough to keep being picked and experienced enough to remain relevant as the squad has changed around him.
That remained the case in 2025–26, when he made 31 league appearances and scored once for St Mirren. He also added one League Cup appearance, three Scottish Cup appearances and two Premiership play-off appearances, scoring once in those play-offs, taking him to 37 appearances and two goals across all competitions for the season.
Fraser’s career has run from Celtic’s youth ranks to Ross County and then into a long St Mirren spell. It is at St Mirren, rather than at the club where he started, that he has built the bulk of his senior record.
