Fabien Dagneaux (born 25 October 1972) is a French football manager. He is the current manager of Ligue 2 club Boulogne. Hired in February 2023 with the team at risk of relegation to Championnat National 3, he led them to Ligue 2 in 2025 via two consecutive promotions.
Born in Boulogne-sur-Mer, Dagneaux was manager of US Boulogne's reserve team, who played for several seasons in the Championnat National 3 (fifth tier of French football). On 8 February 2023, Christophe Raymond was sacked from the first team, who were bottom of the Championnat National 2; Dagneaux was installed as his replacement with Antony Lecointe as his assistant. [1] He won 3–2 away to Metz reserves on his debut three days later and ended the season with safety from a second consecutive relegation. [2]
In 2023–24, Boulogne won promotion to the Championnat National as champions, and Dagneaux's contract was extended. He had previously been a sports instructor employed by the council of Desvres. [3]
Boulogne came third in the 2024–25 Championnat National, qualifying for a promotion playoff against Clermont of Ligue 2. Despite a 4–3 aggregate loss, they were promoted due to the disqualification of Ajaccio from the league above, reaching the professional leagues for the first time in 13 years. [4] On his debut in the competition on 15 August, his team lost 1–0 away to Nancy. [5]
