Triplophysa is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera (Hedinichthys, Indotriplophysa, Labiatophysa, Qinghaichthys and Tarimichthys), but following Kottelat and the Catalog of Fishes are treated as genera in .FishBase, however, includes these in Triplophysa.
Triplophysa zhaoi holds the record for the lowest altitude for Asian fish: it is found at 50 m (160 ft) below sea level in swamps of the Lükqün oasis, in the Turpan Depression in Xinjiang. In the other end, Triplophysa stolickai holds the record altitude for Asian fish: it is found at 5,200 m (17,100 ft) above sea level in hot springs near the Longmu Lake in western Tibet.Triplophysa dalaica has been used as model species to study adaptation to high-altitude hypoxia and 13 positively selected genes involved in hypoxia response have been identified. Some species are blind cave-dwellers.
