1. Mexican territory is one of the centers of origin and dispersion of the genus Opuntia, where several of its species have been an important plant resource for people in arid and semi-arid zones. Opuntia streptacantha is widely distributed in Mexico, however, precise aspects of its geographic distribution and ecological status are still unknown. 2. Here, we modeled its potential distribution under paleoclimatic, current, and future conditions through maximum entropy and predictions from 825 records and seven environmental variables. 3. Potential distribution of Opuntia streptacantha in the interglacial period was contracted and slightly north than current distribution, with 42,850 km2 of optimal habitat including 27 km2 of very suitable habitat. 4. In other periods the central location of potential distribution coincides with the actual current distribution, but the period of the last glacial maximum was characterized by 282 km2 of very suitable habitat, absent in current and future periods. 5. Synthesis and applications. Our findings are relevant in the identification of regions where O. streptacantha may exist but has not yet been detected, in areas where it can potentially spread, suitable habitats due to climate change, and in the selection of areas for protection, conservation, and reproduction of species resistant to the hostile conditions of arid and semi-arid zones of Mexican territory, where the structure and composition of the vegetation will be affected in the next 100 years.
