The Prix de Guiche is a Group 3 flat horse race in France open to three-year-old thoroughbred colts. It is run over a distance of 1,800 metres (about 1⅛ miles) at Chantilly in May.

History
The event is named after Antoine IX (1789–1855), the Duc de Guiche (and later Duc de Gramont), who founded the successful Haras de Meudon stud farm.

The Prix de Guiche was established in 1865, and it was originally held at Longchamp. It was usually contested over 2,000 metres. It was cancelled because of the Franco-Prussian War in 1871. It was run over 2,200 metres in 1873.

The race was abandoned throughout World War I, with no running from 1915 to 1918. It was staged at Maisons-Laffitte in 1944 and 1945. It was cut to 1,950 metres in 1953.

With the exception of four editions over 1,850 metres (1963 and 1965–67), the event continued over 1,950 metres until 1986. It reverted to 1,850 metres in 1987. It was transferred to Chantilly and shortened to 1,800 metres in 2005.

The Prix de Guiche can serve as a trial for the Prix du Jockey Club. Sixteen horses have won both races. The first was Consul in 1869, and the most recent was Vadeni in 2022.
