The 1939 New York World's Fair took place at Flushing Meadows–Corona Park in Queens, New York, United States, during 1939 and 1940. The fair included pavilions with exhibits by 62 nations, 34 U.S. states and territories, and over 1,300 corporations. The exhibits were split across seven zones (including an amusement area), and there were also two standalone exhibits. The fair had about 375 buildings when it opened, which were arranged around the fair's theme center, the Trylon and Perisphere. Buildings were color-coded based on the zone where they were located.

The New York World's Fair Corporation (WFC) oversaw the 1939 fair and leased out the land to exhibitors. The WFC built about 100 buildings, which were developed in a classical style, while the remaining buildings were constructed in a variety of styles. Most of the world's major nations had exhibits, and the fairground also hosted exhibits from states, corporations, and various groups. After the fair, some pavilions were preserved or relocated, but the vast majority of structures were demolished.
