The 2011–12 Division 1 Féminine season was the 38th since its establishment.Lyon are the defending champions. The league schedule was announced on 31 March 2011 and the fixtures were determined on 10 June. The season began on 3 September 2011 and ended on 2 June 2012. The winter break was in effect from 11 December 2011 to 7 January 2012.
There will be three promoted teams from the Division 2 Féminine, the second level of women's football in France, replacing the three teams that were relegated from the Division 1 Féminine following the 2010–11 season. A total of 12 teams will compete in the league with three clubs suffering relegation to the second division, Division 1 Féminine.
La Roche-sur-Yon was the first club to suffer relegation from the first division to the Division 2 Féminine. The club's impending drop occurred on 17 May 2011 following the team's 6–1 defeat to Paris Saint-Germain. The negative result made it mathematically impossible for La Roche-sur-Yon to seize the ninth position in the table, which would have allowed the club to remain in the first division. On the final day of the league season, both Le Mans and Toulouse were relegated to the second division. Toulouse were relegated after losing 5–1 to the champions Lyon. Le Mans drew 0–0 with Saint Étienne, but were unable to pass Yzeure, whom it was equal on points with, in the standings due to goal difference.
Vendenheim was the first club from the Division 2 Féminine to earn a place in the first division after winning Group A of the league. Vendenheim won its group by a 20-point margin. Soyaux was the second club to earn its place in the first division after defeating ES Blanquefort 4–0 win two matches to spare in its group. Vendenheim will be making its return to the first division after two seasons in the second division, while Soyaux will be back in the first division after only one season in the league. AS Muret earned promotion to the first division with only one match to spare after Aulnat Sportif 3–0 at home. On 15 June 2011, the French Football Federation ruled against Muret's promotion due to the club's non-utilization of a youth academy. Second-place club FCF Monteux was subsequently inserted in Muret's place. A day after the announcement, Muret released a press release on its official website announcing its intent to appeal the ruling at the CNOSF, the National Sporting Committee of France which governs sport in France. On 18 July, the CNOSF ruled in favor of Muret allowing the club to retain its promotion to the Division 1 Féminine.
On 18 August 2011, the presidential hierarchy of men's professional club En Avant de Guingamp and women's club Stade Briochin announced that the clubs had 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.
