The Eternal Light Flagstaff is a memorial monument located in Madison Square Park in Manhattan, New York City which was dedicated on Armistice Day, November 11, 1923, and commemorates the return to the United States of members of the United States armed forces who fought in World War I, who were officially received by the city on that site in 1918.

The memorial was commissioned by department store magnate Rodman Wanamaker and cost $25,000 to construct.

The pedestal is inscribed with the sites of battles, as well as a tribute to those soldiers, sailors and marines who died in the war.
