Prix Jean Prat
|}

The Prix Jean Prat is a Group 1 flat horse race in France open to three-year-old thoroughbred colts and fillies. It is run at Deauville over a distance of 1,400 metres (about 7 furlongs), and it is scheduled to take place each year in early July.

History
The event was established in 1858. It was originally the opening leg of a two-part series called the Prix Biennal. The second leg, for horses aged four or older, was first run in 1859. Both races were staged at Longchamp.

The three-year-olds' division of the Prix Biennal was run over 2,000 metres. For a period it was held in April, and it served as a trial for the Prix du Jockey Club.

Both Prix Biennal races were renamed the Prix Jean Prat in 1940. This was in memory of Jean Prat (1847–1940), a successful racehorse owner and breeder.

The version for three-year-olds was switched to late May or early June in 1961. It was shortened to 1,850 metres in 1962. It was transferred to Chantilly and cut to 1,800 metres in 1967. The present system of race grading was introduced in 1971, and for several years the event held Group 2 status.

The race was promoted to Group 1 level in 1985. From this point the version for older horses was known as the Prix Vicomtesse Vigier. The Prix Jean Prat returned to Longchamp in 1986.

The event returned to Chantilly in 1995, and was cut to 1,600 metres and moved to early July in 2005. The distance was further reduced to 1,400 metres in 2019 and the event was moved to a new home at Deauville.
