Brooklyn Borough Hall is a building in Downtown Brooklyn, New York City. It was designed by architects Calvin Pollard and Gamaliel King in the Greek Revival style, and constructed of Tuckahoe marble under the supervision of superintendent Stephen Haynes.

It was completed in 1848 as the City Hall for the City of Brooklyn. In January 1898 the independent City of Brooklyn merged with the City of New York, and Kings County became the Borough of Brooklyn, at which time the building became Brooklyn Borough Hall.
