Vancleavea is a genus of extinct, armoured, non-archosaurian archosauriform with relatively small limbs from the Late Triassic of western North America. The type and only species is V. campi, named by Robert Long & Phillip A Murry, 1995. A nearly complete and articulated skeleton was discovered at the Coelophysis Quarry in north-central New Mexico (Ghost Ranch), USA, and was prepared at the Ruth Hall Museum of Paleontology in Abiquiú, New Mexico before being formally described in the Zoological Journal of the Linnean Society in 2009. Vancleavea was first discovered in 1962 from the Petrified Forest Member of the Petrified Forest National Park and initially described by Long and Murry in 1995. The genus is named after Phillip Van Cleave, who discovered the first known remains of the genus.
