The Prix Jean de Chaudenay was a Group 2 flat horse race in France open to thoroughbreds aged four years or older.
It was run at Saint-Cloud over a distance of 2,400 metres (about 1½ miles), and it was scheduled to take place each year in May or June.
The event was established in 1920, and it was originally called the Grand Prix du Printemps.
The race was renamed in memory of Jean de Chaudenay (1870–1967), a former president of the Société Sportive d'Encouragement, in the late 1960s.
The present system of race grading was introduced in 1971, and the Prix Jean de Chaudenay was classed at Group 2 level.
