The Museum Picasso, or the Picasso Museum, is a museum dedicated to the Spanish artist Pablo Picasso located in Barcelona, Catalonia, Spain. It was inaugurated in 1963 and houses one of the most extensive collections of his works.

The museum is housed in five adjacent medieval palaces in the Gothic Quarter of Barcelona. The buildings were originally constructed between the 13th and 15th centuries and were renovated to accommodate the museum. The museum contains over 4,000 works of art by Picasso, including paintings, sculptures, drawings, and engravings.

The collection is organized chronologically, allowing visitors to see the evolution of Picasso's work over time. It begins with his earliest works from his teenage years and ends with his late works, including the famous Las Meninas series, in which he reinterpreted and recreated Diego Velázquez's famous painting.

In addition to Picasso's works, the museum also houses works by some of his contemporaries, including Joan Miró, Salvador Dalí, and Julio González. There are also several temporary exhibitions each year that explore different aspects of Picasso's life and art.

The museum is an important cultural institution in Barcelona and attracts thousands of visitors each year. It is a must-visit destination for art lovers and anyone interested in the life and work of one of the most important artists of the 20th century.
