The Waldorf Astoria New York is a luxury hotel in Manhattan, New York City.
 The hotel has been housed in two historic landmark buildings in New York.
 The first, bearing the same name, was built in two stages, as the Waldorf Hotel and the Astoria Hotel, which accounts for its dual name.

 It was demolished in 1929 to make way for the construction of the Empire State Building.
 The present building, at 301 Park Avenue between 49th and 50th Streets in Midtown Manhattan, is a 47-story 190.5 m Art Deco landmark designed by architects Schultze and Weaver, which was completed in 1931.
 The current hotel was the world's tallest hotel from 1931 until 1963, when it was surpassed by Moscow's Hotel Ukraina by 7 m .
 An icon of glamour and luxury, the current Waldorf Astoria is one of the world's most prestigious and best known hotels.
 Waldorf Astoria Hotels and Resorts is a division of Hilton Hotels, and a portfolio of high-end properties around the world, now operate under the name, including New York.
