The Prix Messidor is a Group 3 flat horse race in France open to thoroughbreds aged three years or older. It is run at Maisons-Laffitte over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in July.
The event was established in 1949, and it was originally held at Saint-Cloud. It was initially called the Prix de Messidor, a name derived from messis, the Latin word for "harvest". The present title, without the "de", was introduced in 1955.
For a period the race was switched between Maisons-Laffitte (1963âÂÂ65, 1968âÂÂ69) and Saint-Cloud (1966âÂÂ67, 1970âÂÂ72). It began a longer spell at Maisons-Laffitte in 1973.
The race was transferred to Deauville in 1997. It returned to Maisons-Laffitte in 2005.
