Mathias Serin (born 1 August 1991) is a French professional footballer who plays as a midfielder for Championnat National 2 club Colomiers.
Serin began playing football in the youth system of Bordeaux. He played amateur football before turning professional with Ligue 1 club Angers at age 23.[1]
After making his debut in the French lower divisions, Serin joined Angers in June 2015.[2] He made his full professional debut a few months later, in a 1–0 Ligue 1 victory over Troyes, coming up as a late game substitute for Abdoul Camara.[3]
After he left Angers, Serin played semi-pro football with Dunkerque, and the club's supporters chose him as player of the month for December 2017.[4] One season later, he joined local rivals Boulogne.[5] In November 2019 he left Boulogne for Le Puy.[6]
