The 2011–12 season is the 86th campaign in the history of the French association football club Chamois Niortais. It is their second consecutive season in the Championnat National, the third tier of French football, after an 11th-place finish in 2010–11. Former Niort midfielder Pascal Gastien remained as manager, having been appointed to the position in 2009. Niort finished as runners-up in the Championnat National, thereby earning promotion to Ligue 2 for the 2012–13 season after a four-year absence from the second tier of French football.
