The Ford Building, a Streamline Moderne structure in Balboa Park, San Diego, California, serves as the home of the San Diego Air & Space Museum. The building was built by the Ford Motor Company for the California Pacific International Exposition, which was held in 1935 and 1936. The Ford Motor Company built a total of five exposition buildings for the world's fairs. This is the last remaining structure.

Streamline Moderne is an international style of Art Deco architecture and design that emerged in the 1930s. Inspired by aerodynamic design, it emphasized curving forms, long horizontal lines, and sometimes nautical elements. In industrial design, it was used in railroad locomotives, telephones, toasters, buses, appliances, and other devices to give the impression of sleekness and modernity.
