Equus semplicatus was a Pleistocene species of New World stilt-legged horse,^[2] and considered the type species for the stilt legged horses, one of three lineages of equids within the Americas,^[3] the other two being hippidionid and caballine horses.^[4] Now extinct, Equus semiplicatus once inhabited North America.^[5]

Fossils found William's Cave in Texas have been identified as Equus semiplicatus.^[5]
