The Big Bend slider (Trachemys gaigeae) is a species of aquatic turtle endemic to the Southwestern United States and northern Mexico.

T. gaigeae is native to the United States in the states of New Mexico and Texas, and to northern Mexico in the state of Chihuahua. It is found primarily in the Rio Grande and Rio Conchos river systems.

The epithet, gaigeae, is in honor of American herpetologist Helen Beulah Thompson Gaige, who collected the first specimen in the Big Bend region of Texas in 1928.^[1]

The species was first described by professor of zoology at the University of Michigan, Dr. Norman Edouard Hartweg, in 1939. It was for a time considered to be a species of cooter, genus Pseudemys, and then a subspecies of the pond slider, Trachemys scripta, but it was granted full species status, though many sources still refer to it by its various synonyms.
