The National Art Museum of Catalonia (Catalan: Museu Nacional d'Art de Catalunya), abbreviated as MNAC, is a museum of Catalan visual art located in Barcelona, Spain. It is housed on the Palau Nacional, built for the 1929 World's Fair. Situated on the Montjuïc hill at the end of Avinguda de la Reina Maria Cristina, it was rehabilitated by the 1992 Summer Olympics.

The museum was created in 1990, when the Catalonian Museum Law reunited the collections of the former Museu d'Art de Catalunya and the Museu d'Art Modern, adding also the Gabinet de Dibuixos i Gravats, the Gabinet Numismàtic de Catalunya and the Biblioteca d'Història de l'Art (Art History Library). On 1996, the Department of Photography was created.
