This is a list of Texas mammals, those mammals native to or immediately off the coast of the state of Texas in the United States.
Having a mild climate and a range of biomes, from plains and grassland in the north, forests and swamps in the east, mountains in the far west, desert in the west and south, and an extensive coastline, makes Texas home to a wide variety of mammal species. Its central location in the United States makes it a convergence point for the ranges of many species found in the east and west, as well, with its proximity to Mexico, Texas serves as a northern range for several Central American species. While there are also many species endemic to Texas itself.
Texas recognizes three species as their official mammal, including the nine-banded armadillo, the Texas longhorn, and the Mexican free-tailed bat. State law protects numerous species. Those considered threatened species are denoted by (T) and those considered endangered species denoted by (E). Some species are believed to be extirpated from the state, denoted with (X). Several species have been introduced to Texas, and established permanent populations, denoted with (I).
