Kings County Savings Bank is a former bank building at 135 Broadway in the Williamsburg neighborhood of Brooklyn in New York City. It is an example of French Second Empire-style architecture. Construction of the building began in 1860, to designs of William H. Willcox of Brooklyn, in partnership with prominent New York architect Gamaliel King, working as King & Willcox. The structure was continuously occupied by banks until the 1990s. The Williamsburg Art & Historical Center has operated the building since 1996.

Broadway is an avenue in the New York City borough of Brooklyn that extends from the East River in the neighborhood of Williamsburg in a southeasterly direction to East New York for a length of 4.32 miles (6.95 km). It was named for the Broadway in Manhattan. The East New York terminus is a complicated intersection with East New York Avenue, Fulton Street, Jamaica Avenue, and Alabama Avenue. The BMT Jamaica Line of the New York City Subway runs on elevated tracks over Broadway from the Williamsburg Bridge to East New York on its way to Queens. Broadway forms the boundary between the neighborhoods of Bushwick, which lies above Broadway to the northeast, and Bedford–Stuyvesant, which is to the southwest.
