Jacco Macacco was a fighting ape or monkey who was exhibited in monkey-baiting matches at the Westminster Pit in London in the early 1820s. He achieved some measure of fame among the sporting community through his reputed prodigious record of victories against dogs, but was brought to wider attention by depiction in popular literature, artworks and by citation in speeches to Parliament by the animal welfare campaigner Richard Martin. Jacco's most famous fight, against the equally well-known bitch Puss, seems to have marked the end of his career: he may have died as a result of injuries received during the match or of an unrelated illness sometime afterwards. His ashes are claimed to be housed at the True Crime Museum in Hastings, East Sussex.
