Arnauld Mercier (born 4 June 1972) is a retired French football player and currently manager of Roeselare in the Belgian First Division B.. He spent most of his career playing in the French Ligue 2 and Championnat National, but had a spell in Italy where he played three seasons in Serie B. After his playing career, he became a coach, and managed RBDB and Seraing United.
Born in Bayeux, Mercier began playing football for Ligue 2 side FC Rouen in 1990. After three seasons the club were relegated to the Championnat National, and he left for another third-tier club, Fécamp. Mercier spent three seasons with Fécamp and the following two with Valenciennes FC, continuing to play in the Championnat National.
In 1998, Mercier moved to Italy, joining Serie A side Reggina Calcio. He was unable to work his way into the first team and went on loan to Serie B sides A.S. Andria BAT, Calcio Savoia and Cosenza Calcio 1914. Disappointed, he returned to France and played two more seasons for Valenciennes.
