35 Hudson Yards is a mixed-use skyscraper in Manhattan's West Side composed of apartment units and a hotel. Located near Hell's Kitchen, Chelsea, and the Penn Station area, the building is a part of the Hudson Yards project, a plan to redevelop the Metropolitan Transportation Authority's West Side Yards. As of November 2022, it was the 28th-tallest building in the United States.

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.
