The Prix Fille de l'Air is a Group 3 flat horse race in France open to thoroughbred fillies and mares aged three years or older.
It is run at Toulouse over a distance of 2,100 metres (about 1 mile and 2½ furlongs), and it is scheduled to take place each year in November.
The event is named after Fille de l'Air, a successful French-trained filly in the 1860s.
The Prix Fille de l'Air was cancelled twice during World War II, in 1940 and 1941.
The present system of race grading was introduced in 1971, and the Prix Fille de l'Air was classed at Group 3 level.
