Bernard Casoni (born 4 September 1961 in Cannes, France) is a football manager and former player, who played as a defender. In his playing career he played for Olympique Marseille and France at Euro 1992. He was most recently the manager of Ligue 1 side FC Lorient.
In January 2010, Casoni was named manager of Évian Thonon Gaillard FC whom he guided two successive promotions. In his first year, Championnat National side Évian reached the top of the league and then promoted to the Ligue 2 in the next season. In the 2010–11 Ligue 2, Évian won the Champion titles for the second straight year and secured promotion to the Ligue 1 for the first time since established in 2003. He voluntarily resigned from his position on 2 January 2012 in the winter break of the season.
On 10 June 2015, Casoni was appointed as the coach of the Hungarian League club Videoton FC of Székesfehérvár. On 19 August 2015, Casoni was sacked from Videoton after 4 defeats in 5 Nemzeti Bajnokság I matches in the 2015–16 season and after 1 victory and 2 draws and 1 defeat in the 2015–16 UEFA Champions League. Casoni's early farewell was hugely affected by the resignation of the club director of Videoton, Győző Burcsa.
In an interview with the Hungarian sport magazine, Nemzeti Sport, Casoni said that he was disappointed by Videoton since the club let their key players (Nikolić, Calatayud, and Sándor) to be signed by other clubs and no new quality players were signed to replace them. In the interview, he also said that players like Ádám Gyurcsó and István Kovács were of mediocre quality.
