A playoff has not decided relegation and promotion in France's top-two leagues since 1993.
The final relegation and promotion place between Ligue 1 and Ligue 2 will be decided by a playoff next season, the Ligue de Football Professional (LFP) confirmed.
In a statement released Thursday by the LFP, the French league's governing body said playoffs will be reinstated, with the 18th-placed team in the 20-club Ligue 1 to face the team that finished third in the second division.
The Ligue 2 club will host the first leg in 2016-17.
A playoff has not decided relegation and promotion since Valenciennes dropped down from the top flight for Cannes in 1993.
