FC Luxembourg City

The club was founded as a result of merger on 26 March 2004 after a fusion between FC Hamm 37 and FC RM 86 Luxembourg. They spent their first seasons in the Second Division but clinched promotion to the Luxembourg National Division after the 2006–07 season.

FC RM (Rapid Mansfeldia) 86 Luxembourg was itself founded after FC Rapid Neudorf (founded in 1909) and FC Mansfeldia Clausen-Cents (founded in 1919) merged in 1986 after both clubs were relegated from their respective divisions. FC Hamm 37 was founded in 1937. At around the end of the 2021–22 season, the club changed its name to F.C. Luxembourg City with the new branding unveiled before the 2022–23 season.
