The Mohawk Dunes fringe-toed lizard (Uma thurmanae) is a species of phrynosomatid lizard endemic to the U.S. state of Arizona.

[1][2] Its name is a reference to American actress Uma Thurman, as both a pun on the genus name Uma as well as a tribute to the actress for her conservation advocacy.

[3] It is a cryptic species with few fixed morphological differences from other members of Uma, but has statistical morphological differences, and is also genetically distinct from the rest of the genus according to mtDNA.

It is thought to be the most basal member of the Uma notata species complex.
