The Williamsburgh Savings Bank was a financial institution in Brooklyn, New York, from 1851 to 1986. The bank was incorporated in 1851 under legislation passed by the New York State Assembly. The bank continued to operate until a series of mergers brought the bank into the HSBC group late in the 20th century.

The Williamsburgh Savings Bank Tower, also known as One Hanson Place, is a skyscraper in the Fort Greene neighborhood of Brooklyn in New York City. Located at the northeast corner of Ashland Place and Hanson Place near Downtown Brooklyn, the tower was designed by Halsey, McCormack & Helmer and constructed from 1927 to 1929 as the new headquarters for the Williamsburgh Savings Bank. At 41 stories and 512 feet (156 m) tall, the Williamsburgh Savings Bank Tower was the tallest building in Brooklyn until 2009.
