National Flag Square is a large city square off Neftchiler Avenue in Bayil, Baku, Azerbaijan. A flag measuring 70 by 35m flies on a pole 162m high. The flagpole was confirmed as the world's tallest by the Guinness Book of Records, but was soon overtaken by the 165 m Dushanbe Flagpole in Tajikistan. Both flagpoles were built by the same American affiliated company, Trident Support.
National Flag Square covers 60ha overall. The area of the upper part is 3ha. The square features the state symbols of Azerbaijan—the coat of arms and the anthem—and a map of the country.
