The Larco Museum (Spanish: Museo Arqueológico Rafael Larco Herrera) is a privately owned museum of pre-Columbian art, located in the Pueblo Libre District of Lima, Peru. The museum is housed in an 18th century vice-royal mansion built over a 7th century pre-Columbian pyramid. It showcases chronological galleries that provide a thorough overview of 4,000 of Peruvian pre-Columbian history. It boasts one of the world's largest collections of pre-Columbian art including Moche, Nazca, Chimú, and Inca pieces. Additionally, the Larco Museum is well known for its gallery of pre-Columbian erotic pottery.

It was one of the first museums in the world to make its entire 45,000 piece collection available in an online electronic catalog.

In 1925, Rafael Larco Herrera acquired a collection of vases and other archaeological pieces from Alfredo Hoyle, who was his brother-in-law. There were approximately 600 ceramic pieces in all. The arrival of these objects ignited a collector's enthusiasm in his son, Rafael Larco Hoyle. Soon after, Larco Herrera left his son in charge of the collection and those pieces completed the first collection of what would become the Rafael Larco Herrera Museum.
