USS Hydraulic (SP-2584) was a United States Navy patrol vessel in commission from 1918 to 1919. Hydraulic was built in 1900 as a steam yacht by the A. C. Brown Shipbuilding Company at Tottenville on Staten Island, New York. On 29 May 1918, the U.S. Navy acquired Hydraulic under a bareboat charter from her owner, Max Zickel of Hoboken, New Jersey, for use as a section patrol boat during World War I. She was commissioned as USS Hydraulic (SP-2584) on 17 August 1918 with Chief Quartermaster R. F. Supper in command. The Navy returned Hydraulic to Zickel on 23 January 1919.
