The Solow Building, also known as 9 West 57th Street, is a skyscraper in the Midtown Manhattan neighborhood of New York City. Completed in 1974 and designed by Gordon Bunshaft of Skidmore, Owings & Merrill, it is west of Fifth Avenue between 57th and 58th Streets, overlooking the Plaza Hotel and Central Park. The building measures 689 feet (210 m) tall with 50 stories. 9 West 57th Street was developed by Sheldon Solow, who named the building after himself and continued to manage and own the building until his death in 2020.

Gordon Bunshaft was an American architect, a leading proponent of modern design in the mid-twentieth century. A partner in Skidmore, Owings & Merrill (SOM), Bunshaft joined the firm in 1937 and remained with it for more than 40 years. His notable buildings include Lever House in New York, the Beinecke Rare Book and Manuscript Library at Yale University, the Hirshhorn Museum and Sculpture Garden in Washington, D.C., the National Commercial Bank in Jeddah, Saudi Arabia, 140 Broadway, and Manufacturers Hanover Trust Branch Bank in New York.
