The Prix de Lutèce is a Group 3 flat horse race in France open to three-year-old thoroughbreds.
It is run at Longchamp over a distance of 3,000 metres (about 1+7⁄8 miles), and it is scheduled to take place each year in early September.
The event is named after Lutetia (in French, Lutèce), a Gallo-Roman city located on the site of what is now Paris.
Its conditions varied, but in its later years it was a 2,400-metre race for horses aged three or older.
The last horse to win both races in the same year was Agent Double in 1984.
