The Prix de Ris-Orangis 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 1,200 metres (about 6 furlongs), and it is scheduled to take place each year in July.
It was originally a 1,600-metre race for horses aged four or older, and it took place in early spring.
At this point it was renamed after Ris-Orangis, a commune in which part of the racecourse was situated.
The Prix de Ris-Orangis was cut to 1,200 metres, switched to July and opened to three-year-olds in 1987.
