Luna Park was an amusement park that operated in the Coney Island neighborhood of Brooklyn in New York City, United States, from 1903 to 1944. The park was located on a site bounded by Surf Avenue to the south, West 8th Street to the east, Neptune Avenue to the north, and West 12th Street to the west. Luna Park was located partly on the grounds of the small park it replaced, Sea Lion Park, which operated between 1895 and 1902. It was the second of the three original, very large, iconic parks built on Coney Island; the others were Steeplechase Park and Dreamland. At Coney Island's peak in the middle of the 20th century's first decade, the three amusement parks competed with each other and with many independent amusements.

Frederic Williams Thompson was an American architect, engineer, inventor, and showman known for creating amusement rides and one of the first large amusement parks.
