The Big Bend slider (Trachemys gaigeae), also called commonly the Mexican Plateau slider and la jicotea de la meseta mexicana in Mexican Spanish, is a species of aquatic turtle in the family Emydidae. The species is native to the Southwestern United States and northern Mexico.

The species Trachemys gaigeae was first described by professor of zoology at the University of Michigan, Dr. Norman Edouard Hartweg, in 1939, as a subspecies, Pseudemys scripta gaigeae. Later, it was assigned to the genus Chrysemys, then to the genus Trachemys. Most recently, it was granted full species status, though many sources still refer to it by its various synonyms.

The Nazas slider (T. hartwegi) of the Nazas River in northern Mexico was formerly considered a subspecies of T. gaigeae, but was reclassified as a distinct species by the Turtle Taxonomy Working Group and the Reptile Database in 2021.
