The Prix Perth is a Group 3 flat horse race in France open to thoroughbreds aged three years or older.
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 October or early November.
The event is named after Perth, a successful racehorse whose career concluded in 1900.
The Prix Perth was abandoned throughout World War I, with no running from 1914 to 1918.
The present system of race grading started in 1971, and the Prix Perth was classed at Group 3 level.
