The Marguerite Stakes was a Thoroughbred horse race at Pimlico Race Course, in Baltimore, Maryland run between 1945 and 1965. A race on dirt for two-year-old fillies, it was created as a companion event to the Pimlico Futurity and declared at the time to be one of the richest of its kind in the United States. It was named in honor of Marguerite, one of the great broodmares in racing history. Marguerite was the dam of four significant runners including Triple Crown winner and U.S. Racing Hall of Fame inductee, Gallant Fox.
