The 1964/1965 New York World's Fair was the second World's Fair to be held at Flushing Meadows Park in the Borough of Queens, in New York City in the twentieth century. It opened on April 22, 1964, and ran for two six-month seasons concluding on October 17, 1965. The World's Fair took place without sanctioning from the Bureau of International Expositions, the only one to do so.
