Passaic County Court House, Courthouse in Paterson, United States

The Passaic County Court House complex in Paterson comprises three buildings on Hamilton and Grand Streets. The Old Court House at 71 Hamilton Street, built 1898–1903 to Samuel Burrage Reed's Classical Revival design, stands beside the 1899 former U.S. Post Office at 63-65 Hamilton Street, a Dutch Baroque Revival work by Fred Wesley Wentworth annexed by the county in 1936. A 1968 court house at 77 Hamilton Street and a 1994 administration building at 401 Grand Street complete the group.

The Old Passaic County Court House was built between 1898 and 1903 to designs by architect Samuel Burrage Reed. The neighbouring annex at 63-65 Hamilton Street went up in 1899 as the United States Post Office, designed by Fred Wesley Wentworth in Dutch Baroque Revival style. The county bought that building in 1936 and rededicated it as the Passaic County Administration Building, attaching it to the courthouse. Both buildings were listed on the historic registers in 2015.
