Eclair au Chocolat (1935 – ca. 1945) was a French Thoroughbred racehorse and sire. As a three-year-old he won the Grand Prix de la Ville de Vichy and then established himself as one of the best of a strong generation of European horses with wins in the Prix Royal Oak and the Prix de l'Arc de Triomphe. After retiring to stud in 1939 he was taken to Germany during the Occupation of France. His final fate is unknown.
