Hephestion (foaled 1807) was a British Thoroughbred racehorse and best known for winning the classic 2000 Guineas in 1810. The rest of his racing career was undistinguished, as he recorded only four other victories in minor contests from a total of eighteen competitive races. He does not appear to have found a place at stud as a breeding stallion.
