Fine Arts Museums of San Francisco, Art museum in Golden Gate Park, San Francisco, United States.

The Fine Arts Museums of San Francisco is a nonprofit organization operating two locations: the de Young Museum in Golden Gate Park and the Legion of Honor in Lincoln Park. Both buildings display paintings, sculptures, photographs, and decorative arts from different periods and regions around the world.

The de Young originated in the California Midwinter International Exposition of 1894 and opened in 1895 as the Memorial Museum; it was renamed for newspaper publisher Michael Henry de Young. The Legion of Honor opened in 1924 in George Applegarth's Beaux-Arts building, inspired by the French pavilion of the 1915 Panama-Pacific International Exposition. The two were informally united in 1931 under director Lloyd LaPage Rollins and formally merged in 1972. The present copper-clad de Young building by Herzog & de Meuron opened in October 2005.

The de Young holds American art from the 17th century to today, plus textile arts and costumes, African art, Oceanic art, arts of the Americas, and contemporary art. The Legion of Honor shows European painting, sculpture, and decorative arts, ancient art, graphic arts, and contemporary art alongside its Beaux-Arts building.

The two museums are located in different neighborhoods and require separate visits with separate travel. Both sites offer exhibition spaces on multiple levels, outdoor gardens, and seating areas to rest between galleries.

The de Young Museum includes an observation tower that offers visitors an open view over the park and the city. The copper cladding on the facade changes color over time and gradually develops a greenish patina.
