The Texas black-tailed jackrabbit (Lepus californicus texianus) also known as the Texan black-tailed jackrabbit, Texian black-tailed jackrabbit, Texas jackrabbit, Texian hare, or the Texan jackrabbit, is a subspecies of the black-tailed jackrabbit that is native to parts of Texas, and the southwest United States, northern Mexico, and some occasional parts of central Mexico.

Synonyms
The Texas black-tailed jackrabbit has one accepted synonym; being Lepus texianus (Texas jackrabbit) by John James Audubon and John Bachman in the Viviparous Quadrupeds of North America. The species taxonomic rank was then lowered to a subspecies rank, for the Texas black-tailed jackrabbit looked almost exactly the same as the common black-tailed jackrabbit.
