Lear Fan (2 February 1981 – 7 July 2008) was an American-bred, British-trained Thoroughbred racehorse and sire. One of an exceptionally strong generation of European racehorses he was one of the leading two-year-olds when he was unbeaten in three races including the Champagne Stakes. In the following year he defeated Rainbow Quest in the Craven Stakes before finishing third to El Gran Senor and Chief Singer in the 2000 Guineas. He recorded his most valuable success later that year when defeating Palace Music in the Prix Jacques Le Marois. At the end of his three-year-old season he was retired to stud in Kentucky where he proved to be a successful sire of winners. He was retired from stud duty in 2004 and died four years later.
