Xantusia is one of three genera of night lizards (family Xantusiidae). Species of Xantusia are small to medium-sized, viviparous (live-bearing) lizards found in the U.S. Southwest and in northern Mexico.


The names and descriptions of the genus and the type species were published in 1859 by Spencer Fullerton Baird, the generic name commemorating the naturalist John Xantus.[1][2]


The following is a list of species in the genus.[1]
