USS Nyack was a wooden-hulled screw gunboat of the United States Navy, that saw action in the American Civil War. The ship was laid down at New York Navy Yard in 1863, launched on 6 October 1863, and commissioned on 28 September 1864, Lieutenant Commander L. Howard Newman in command.

Civil War, 1864–1865
Nyack joined the North Atlantic Blockading Squadron off Wilmington, North Carolina, for duty through the close of the Civil War. She joined in attacks on Fort Fisher in the Cape Fear River on 24 and 25 December 1864, and participated in the capture of Fort Anderson nearby on 18 and 19 February 1865.

Pacific, 1866–1871
Ordered to the Pacific in 1866, Nyack cruised the coasts of Ecuador, Peru, and Chile, protecting American nationals while maintaining American neutrality during tension between Spain and her former colonies. She gave asylum to General Manuel Pardo, ex-President of Peru, on 10 January 1868 as he fled revolutionary turmoil, carrying him safely to Valparaíso. After similar service to America's foreign relations Nyack returned to San Francisco early in 1871, decommissioning on 15 March 1871. She was sold there to W. E. Mighell on 30 November 1883.
