En Avant Guingamp Feminines are a French football club based in Saint-Brieuc, a commune in the Brittany region. The club was previously the women's section of men's football club Stade Briochin and was founded in 1973 under the name Chaffoteaux Sports Saint-Brieuc. From 1999–2003, the club played under the name Saint-Brieuc Football Feminin, switching to Stade Briochin following the end of the 2002–03 season. The club currently plays in the Division 1 Feminine, the first division of women's football in France, and is coached by Frederic Biancalani.
On 18 August 2011, the presidential hierarchy of men's professional club En Avant de Guingamp and Stade Briochin announced that the clubs reached an agreement on a merger, which will come into effect at the start of the 2011–12 season. Under the agreement, Stade Briochin will dissolve and play as the women's team of Guingamp. All other remnants of the club remain the same, such as its president, manager, and players.
