The Prix Daru was a Group 2 flat horse race in France open to three-year-old thoroughbreds.

It was run at Longchamp over a distance of 2,100 metres (about 1 mile and 2½ furlongs), and it was scheduled to take place each year in mid-April.

[1] It was renamed in memory of Viscount Paul Daru,[2] who served as president of the Société d'Encouragement, in 1877.

The combined event, the Prix Daru-Noailles, was contested over 2,150 metres at Le Tremblay in 1943.

The present system of race grading was introduced in 1971, and the Prix Daru was classed at Group 2 level.
