The Ligue 1 relegation/promotion playoffs is an annual playoff fixture in French football contested by the 18th-placed team in Ligue 1 and the winner of the Ligue 2 promotion play-offs. It takes place after the completion of the regular season and is administered by Ligue de Football Professionnel. Play-offs are a two-legged tie and the winner is decided by aggregate score. Play-offs were introduced in the 2016–17 season, even though similar play-offs were played until 1993 when Ligue 1 was named Division 1. The first leg of play-offs are played on the home ground of the Ligue 2 club with the return leg at the home of the Ligue 1 club.
