Ahualulco is a town and municipality in the Mexican state of San Luis Potosí in central Mexico.

Ahualulco was founded in 1542 by Cristobal de Oñate in a region that had been inhabited in pre-Columbian times by the Chichimeca people.

The community got its start in early 1799 with residents from the nearby La Estancia and Hacienda de Bocas areas.

On August 16, 1859, Ojocaliente was formally denominated a villa as Ahualulco de Pinos.
