Alectrosaurus (meaning “Unmarried Lizard”) is a genus of tyrannosauroid from the Late Cretaceous Period of the Gobi Desert in Mongolia. It is closely related to Tyrannosaurus, but much shorter, at 5 metres (16.4 feet) in length. On 25 April 1923, during the third expedition to Asia of the American Museum of Natural History, assistant paleontologist George Olsen found the holotype. The type species, described by Charles Gilmore in 1933, was named A.olseni, named after George Olsen.
