Mathieu Debuchy (French pronunciation: [matjø dəbyʃi]; born 28 July 1985 in Fretin) is a French footballer who plays for French club Lille in Ligue 1. He is often deployed in the right back position, but began his career playing as a midfielder usually acting as a deep-lying play-maker.

Debuchy began his career playing for his hometown club Union Sportive Frétin before joining Lille at the age of eight. After spending a decade in Lille's youth system, he was promoted to the senior team following the winter break of the 2003–04 season. Debuchy was given the number 33 shirt and simultaneously made his professional debut and first start on 31 January 2004 in a league match against Metz. He played the entire match as Lille recorded a 1–0 win. Debuchy made five more appearances that season, which included two starts and three substitute appearances.

The following season, Debuchy switched to the number 2 and his playing time increased significantly. He appeared in 19 matches and scored three goals. His first professional goal came against Bordeaux. Debuchy scored the goal in the first minute of the match. Lille's solid form that season resulted in the club finishing second in the league and, as a result, qualifying for the UEFA Champions League. Debuchy was also instrumental in Lille's run to the Round of 16 in 2004–05 UEFA Cup where the club was eliminated by rival French club Auxerre.
