The Prix Daphnis is a Group 3 flat horse race in France open to three-year-old thoroughbreds.
The event was established for colts and geldings in 1921 alongside the Prix Chloé, a similar contest for fillies.
The two races were named after the characters Daphnis and Chloe from a work by the Greek novelist Longus.
Both races were originally held at Le Tremblay, and they usually took place in late April or early May.
In 2018 the Prix Daphnis underwent major changes, being opened to fillies, transferred to Deauville's August meeting and reduced to 1,600 metres again.
