Cirsium texanum is a species of plant in the tribe Cardueae within the family Asteraceae found in North America. Common names include Texas thistle, Texas purple thistle or southern thistle. The species is native to northern Mexico (Coahuila, Durango, Nuevo León, San Luis Potosí, Tamaulipas) and the southern Great Plains of the south-central United States (primarily Texas, Oklahoma, and eastern New Mexico with additional populations in Louisiana, Arkansas, and Missouri). It grows in prairies and roadsides.
