The Open Occitanie (formerly known as the Open Sud de France and Grand Prix de Tennis de Lyon) is a professional tennis tournament played on indoor hardcourts. It is currently part of the ATP Tour 250 series of the ATP Tour. Founded in 1987, it was held annually in October at the Palais des Sports de Gerland in Lyon until 2009, before being relocated at the Arena Montpellier in 2010. There was no event in 2011 as the tournament moved to a January slot in 2012.
The current venue now called Sud de France Arena holds 7,500 spectators for tennis events. Since 2025, the tournament is one of three French events of the ATP Tour 250 series, along with the Open 13 and the Moselle Open. It was one of four with the Lyon Open until 2025.
