Hudson Yards is a 28-acre (11 ha) real estate development in the Hudson Yards neighborhood in Manhattan, New York City, between the Chelsea and Hell's Kitchen neighborhoods. It is located on the waterfront of the Hudson River. Upon completion, 13 of the 16 planned structures on the West Side of Midtown South would sit on a platform built over the West Side Yard, a storage yard for Long Island Rail Road trains. The first of its two phases, opened in 2019, comprises a public green space and eight structures that contain residences, a hotel, office buildings, a mall, and a cultural facility. The second phase, on which construction had not started as of 2023, will include residential space, an office building, and a school.

Hudson Yards is a neighborhood on the West Side of Midtown Manhattan in New York City, bounded roughly by 30th Street in the south, 41st Street in the north, the West Side Highway in the west, and Eighth Avenue in the east. The area is the site of a large-scale redevelopment program that is being planned, funded, and constructed under a set of agreements among the State of New York, City of New York, and Metropolitan Transportation Authority (MTA), with the aim of expanding the Midtown Manhattan business district westward to the Hudson River. The program includes a major rezoning of the Far West Side, an extension of the New York City Subway's 7 and <7>​ trains to a new subway station at 34th Street and 11th Avenue, a renovation and expansion of the Javits Center, and a financing plan to fund the various components. The various components are being planned by New York City Department of City Planning and New York City Economic Development Corporation.
