Museo Regional Potosino, Archaeological museum in San Luis Potosí, Mexico.

The Museo Regional Potosino is an archaeological museum in San Luis Potosí that displays collections of pottery, skulls, and skeletal remains from the Huasteca region. The collection spans different periods and reveals the long history of settlements across this area.

The building is part of the former convent of San Francisco, constructed in 1586. The Museo Regional Potosino was inaugurated there on 20 November 1952. In 2004 it received the Premio a la Conservación del Patrimonio Cultural for architectural restoration and a reorganisation of its displays.

The exhibits feature objects from multiple indigenous civilizations that inhabited this region, including the Olmec, Totonac, and Mixtec peoples. The artifacts reveal how these cultures lived and what they valued in their daily lives.

The museum sits in Plaza Aranzazú within the historic center and is easy to reach on foot. Plan for at least 90 minutes to explore the permanent exhibits thoroughly.

The Capilla de Aranzazú occupies the upper floor of the former convent and forms one of the museum's four exhibition rooms. Its facade is a representative work of the baroque style, and inside visitors can see an arch decorated with an octagonal window and a Caravaca cross.
