The Prix Isonomy is a Listed flat horse race in France which is open to two-year-old thoroughbreds. It is run at Saint-Cloud over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in late November.



The event is named after Isonomy, a successful racehorse in the late 19th century. It was formerly held at Evry, and it used to take place in late October or early November. For a time it was contested over a length of 2,000 metres, and this was shortened to 1,800 metres in 1990. It was run at Saint-Cloud over 1,600 metres in 1996, and at Longchamp over 1,800 metres for the following two years.

The Prix Isonomy was restored to 1,600 metres in 1999, and since then it has been staged at various different venues. There were brief periods at Maisons-Laffitte (1999–2000), Saint-Cloud (2001–02) and Fontainebleau (2003–04), and it began its current spell at Saint-Cloud in 2005. The race is now usually scheduled for late November.
