USルシタノス・サンモール

US Lusitanos Saint-Maur was founded in 1966 by José Lebre, amongst the Portuguese immigrant community in the town of Saint-Maur-des-Fossés. Initially the club consisted entirely of first generation Portuguese, but before long it needed to recruit second generation immigrants with French nationality in order to expand.

In 1975 Armand Lopes, one of the sponsors of the club, took over and set goals for the club to rise up to the national leagues within five years. This took longer than planned, but they arrived in the newly formed National 3 in 1993, as champions of the Division d'Honneur in the Paris region. They gained promotion to National 2 the following season, and two seasons later reached Championnat National the highest amateur division in the country.

After finishing fourth at the first attempt, the club moved up and down between the Championnat National and Championnat de France Amateur, as National 2 had now become. In the 2001–02 season, back in the Championnat National, they reached the last 16 of the Coupe de France, beating Ligue 1 side Girondins de Bordeaux in the round of 32.

They suffered another relegation back to the CFA in 2002, and due to a failed merger with US Créteil-Lusitanos and failure to properly register the team, they were administratively relegated to the Division Supérieure Régionale of the Paris region, effectively level seven of French football. They remained in regional football for more than a decade. In 2012 Arthur Machado was elected as president, restructuring the club.

The club gained promotion again to Championnat de France Amateur 2 (level 5) in 2015 and to the CFA in 2016.
