The Prix Bertrand du Breuil is a Group 3 flat horse race in France open to thoroughbreds aged four years or older.
It is run at Chantilly over a distance of 1,600 metres (about 1 mile), and it is scheduled to take place each year in June.
It reverted to being a flat race in 1856, when it became a 3,200-metre contest for horses aged three or older.
The Chemin de Fer du Nord continued to provide the total prize money until 1910.
In 2013 the race was renamed in memory of Bertrand du Breuil (1926–2011), the last president of the Societe d'Encouragemment, forerunner of France Galop.
