The Palace of Fine Arts in the Marina District of San Francisco, California, is a monumental structure originally constructed for the 1915 Panama-Pacific Exposition in order to exhibit works of art presented there. One of only a few surviving structures from the Exposition, it is the only one still situated on its original site. It was rebuilt in 1965, and renovation of the lagoon, walkways, and a seismic retrofit were completed in early 2009.

It remains a popular attraction for tourists and locals, and is a favorite location for weddings and wedding party photographs for couples throughout the San Francisco Bay Area, and such an icon that a miniature replica of it was built in Disney's California Adventure in Anaheim.

The Palace of Fine Arts was one of ten palaces at the heart of the Panama-Pacific Exhibition, which also included the exhibit palaces of Education, Liberal Arts, Manufactures, Varied Industries, Agriculture, Food Products, Transportation, Mines and Metallurgy and the Palace of Machinery. The Palace of Fine Arts was designed by Bernard Maybeck, who took his inspiration from Roman and Greek architecture in designing what was essentially a fictional ruin from another time.
