Léo-Lagrange stadium, Sports venue in Chalon-sur-Saône, France.

Léo-Lagrange Stadium is a sports facility in Chalon-sur-Saône with multiple playing fields and training areas for different sports. It contains an athletics track, football and rugby fields, along with courts for basketball and handball.

Construction of the complex began in early 1959 with earthworks: a bank was raised to carry the stands and shelter the pitch from wind. The main stadium was inaugurated in 1964 with a Coupe de France tie between Olympique Lyonnais and Forbach, won 2-0 before 3,824 spectators. The whole complex was inaugurated in 1966, after seven years of work, and was presented in Architecture Française.

The covered stand on the annexe pitch has seats arranged to spell "Chalon". The main stadium hosts the athletics club ECA Chalon, and the venue has long staged Coupe de France football ties on neutral ground, including a 1977 Lyon–Gueugnon match watched by a record 10,000 spectators.

The main stadium sits below an artificial embankment built to shelter the pitch from wind, with the covered stand on that slope and open terraces opposite, split by a central walkway. The athletics track dates from 2017 and was rebuilt to host national competitions. The complex also holds the Louis Brailly rugby pitch and the Jean-Pierre Adams football pitch.

The covered stand of the annex pitch has seats arranged to spell the word "Chalon". The main stadium hosted a Coupe de France round of 32 in 1977 between Olympique Lyonnais and FC Gueugnon, attended by 10,000 spectators, a record for the ground.
