Saint-Denis Saint-Leu FC was a French football club founded in the summer of 1996, following the merger of FC Saint-Leu (which played in the National) with US Saint-Denis, a club from the Division d'honneur.

The goal of the merger was to create a "large suburban club with European ambition",[2] capable of occupying the brand new Stade de France in Saint-Denis, just north of Paris.

[2] At the end of the 1997–1998 season, after only three seasons of existence and due to financial difficulties, the club was administratively relegated to the CFA (Championnat de France amateur).

[3] The following season, despite an 8th-place finish in the CFA, the club was relegated to the Division d'Honneur.

In 1999, the two cities separated and each went their own way back to the Division d'Honneur.
