740 Park Avenue is a luxury cooperative apartment building on Park Avenue between East 71st and 72nd Streets in the Lenox Hill neighborhood of Manhattan, New York City, which was described in Business Insider in 2011 as "a legendary address" that was "at one time considered (and still thought to be by some) the most luxurious and powerful residential building in New York City". The "pre-war" building's side entrance address is 71 East 71st Street.

The 17-story building was designed in an Art Deco architectural style and consists of 31 units, including duplexes and triplexes. The architectural height of the building is 78.03 metres (256.0 ft).

The building was constructed in 1929 by James T. Lee, the grandfather of Jacqueline Kennedy Onassis – Onassis lived there as a child – and was designed by Rosario Candela and Arthur Loomis Harmon; Harmon became a partner of the newly named Shreve, Lamb and Harmon during the year of construction. The building was officially opened in October 1930, but it was not until the 1980s that the building's apartments sold for incredibly high prices. Hedge fund manager David Ganek paid $19 million for the childhood duplex home of Jacqueline Kennedy Onassis in 2005.

In 1937 one of the first well known residents was John D. Rockefeller, Jr., who moved into a triplex that many still consider New York's crown jewel apartment. In 1971 Saul Steinberg bought that apartment for $285,000 and after two divorces sold to Stephen Schwarzman for "slightly above or below $30 million". As of 2000^[update], this was reportedly the highest price ever paid on Park Avenue.
