One Liberty Plaza, formerly the U.S. Steel Building, is a skyscraper in the Financial District of Lower Manhattan in New York City. It is situated on a block bounded by Broadway, Liberty Street, Church Street, and Cortlandt Street, on the sites of the former Singer Building and City Investing Building.

The building was designed in the International Style by Skidmore, Owings & Merrill and completed in 1973. It is 743 ft (226 m) tall and has 54 floors. At 2.3 million sq ft (210,000 m²), each floor offers almost 1 acre (0.40 ha) of office space, making it one of the largest office buildings in New York by usable interior space. Its facade is black, consisting of a structural steel frame. South of the building is Zuccotti Park, formerly called Liberty Plaza Park.

One Liberty Plaza was originally commissioned by U.S. Steel, and also housed the headquarters of Merrill Lynch. A variety of tenants occupy the space, from large law firms to public and not-for-profit agencies like the Lower Manhattan Development Corporation and the World Trade Center Memorial Foundation as well as new businesses. Since 2001 One Liberty Plaza has been owned and operated by Brookfield Properties.
