The original team played in a fully white strip, and competed in the regional championship of the Ligue de Charentes.
[7] The side remained in the DH Centre-Ouest until 1960 when, under the guidance of Nordine Ben Ali,[6] they won the league title by a point ahead of Poitiers FC to return to the CFA.
[9] After being runners-up in the division for two consecutive seasons in 1961–62 and 1962–63, the team secured a number of mid-table league finishes under Kazimir Hnatow.
[9] In April 1984, Patrick Parizon was appointed as manager and the following month, the side secured a third-placed finish to gain promotion back to Division 3.
The next 13 consecutive seasons saw a number of mid-table finishes in Ligue 2, until a poor 2004–05 campaign, in which the team lost 21 of their 38 league matches.
[9] Philippe Hinschberger was appointed as the new manager in 2005,[6] and he successfully escaped from the Championnat National at the first attempt, securing the title with a 2–0 victory over Sporting Toulon Var on 13 May 2006.
[12][14] Denis Troch was hired as the club's new manager in August 2008,[12] and despite hopes of a swift return to Ligue 2, the team performed poorly throughout the 2008–09 campaign.
[15] The relegation saw the end of Chamois Niortais's era as a professional club, as they were forced to become a semi-professional outfit due to the DNCG rules.
[16] In June 2009, Pascal Gastien was appointed as manager for his third spell in charge of the club, handed the task of achieving promotion back to the Championnat National at the first attempt.
[17] The club won the CFA Group C that season, and was subsequently promoted back to the National division for the following campaign.
[citation needed] The following season, the team finished as runners-up in the Championnat National behind Nîmes to return to Ligue 2 for the 2012–13 campaign and regain their professional status.
[citation needed] On 1 August 2024, the club was excluded from national competitions by the DNCG, synonymous with relegation to Régional 1.
In the 2007–08 season the team played in a gold and black kit for the first time, to commemorate 20 years since the club competed in Division 1.
For the 2009–10 season, the club's kits are produced by Italian sportswear company, Erreà, and the main shirt sponsor is Cheminées Poujoulat.
[21] When Chamois Niortais were founded, the club had no fixed home ground and played friendly matches at various venues in and around Niort.
In 1926, when the team joined the Ligue du Charentes, the club adopted the small Stade de Genève as their first home.
[2] They continued to play at the Stade de Genève for the majority of the following 50 years until, in the early 1970s, it was announced that the side would move into a new stadium.
On 3 August 1974, the Stade Venise Verte was opened, with the inaugural game being an exhibition match between Chamois Niortais and Dynamo Kyiv.
[12] The record attendance at the stadium was set on 24 October 1987, when 16,715 people saw Chamois Niortais defeat Marseille by two goals to one in a Division 1 encounter.
[23] The organisation has no history of violence or extremism, and works closely with the football club to try to improve the atmosphere at home matches.
[6] The current manager is Pascal Gastien, who was given the job in 2009 after Denis Troch was sacked following the side's relegation from the Championnat National.
