The Museu Picasso is an art museum in Barcelona, in Catalonia, Spain. It houses an extensive collection of artworks by the twentieth-century Spanish artist Pablo Picasso, with a total of 4251 of his works. It is housed in five adjoining medieval palaces on Montcada Street in the La Ribera neighborhood in the Old City of Barcelona. It opened to the public on 9 March 1963, becoming the first museum dedicated to Picasso's work and the only one created during his lifetime. It has since been declared a museum of national interest by the Government of Catalonia.

Pablo Ruiz Picasso was a Spanish painter, sculptor, printmaker, ceramicist, and theatre designer who spent most of his adult life in France. One of the most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon (1907) and the anti-war painting Guernica (1937), a dramatic portrayal of the bombing of Guernica by German and Italian air forces during the Spanish Civil War.
