The club was formed in 1898 and its achievements are comparatively minor, with their biggest feat to date consisting of reaching the semi-finals during the 1936–37 edition of the Coupe de France, and one Ligue 1 season in 2009–10.

The Coupe de France 1937 competition saw Boulogne reach the semi-finals, but they were convincingly beaten by FC Sochaux 6–0.

Mayor of Boulougne and billionaire Jean Muselet intervened to save the club and appointed Jacques Wattez as chairman.

On 17 March 1999, the club marked their centenary by hosting Liverpool – managed by Gérard Houllier of nearby Thérouanne – in a friendly and winning 2–1.

Boulogne stayed up on the last day of the 2007–08 Ligue 2 season with a last-second win over Chamois Niortais F.C., who needed a draw to avoid the drop themselves.

[6] They stayed just one season, being relegated in 19th place with 31 points; the first of their seven wins was in the second game on 16 August 2009, 2–1 at home to Grenoble Foot 38.

They were denied an opportunity for promotion when the FFF executive committee announced that the usual playoff between 18th in Ligue 2 and 3rd in Championnat National would not go ahead.
