The Prix Eugène Adam is a Group 2 flat horse race in France open to three-year-old thoroughbreds.
It is run at Maisons-Laffitte over a distance of 2,000 metres (about 11⁄4 miles), and it is scheduled to take place each year in July.
The event was renamed in memory of Eugène Adam (1840–1904), a former president of the Société Sportive d'Encouragement, in 1911.
The Prix Eugène Adam was abandoned throughout World War I, with no running from 1915 to 1918.
Due to the 2019–20 coronavirus pandemic, 2020 Prix Eugène Adam are not run.
