The F. Eugene Dixon, Jr. Cotillion Handicap is an American Thoroughbred horse race held annually at Parx Racing and Casino in Bensalem, Pennsylvania. Since 2010, it has been raced on the first Saturday in October as a prelude to the annual Breeders' Cup World Thoroughbred Championships. Prior to this change in date, it was held in September or October, usually a week or two before the Breeders' Cup; the new date annually attempts to draw a stronger field.
