56 Beaver Street is a structure in the Financial District of Manhattan in New York City, United States. Designed by James Brown Lord, the building was completed in 1891 as a location of the Delmonico's restaurant chain. The current building, commissioned by Delmonico's chief executive Charles Crist Delmonico, replaced Delmonico's first building on the site, which had been built in 1837. The building is a New York City designated landmark and a contributing property to the Wall Street Historic District, a National Register of Historic Places district.
