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.
