USS Knickerbocker (SP-479), was a United States Navy tug, minesweeper, and dispatch ship in commission from 1917 to 1919.

The U.S. Navy leased Knickerbocker from her owner, the Cornell Steamboat Company of New York City, on 2 May 1917 for use during World War I and enrolled her in the Navy Coast Defense Reserve, then purchased her outright from Cornell Steamboat on 13 September 1917.

Assigned to the 3rd Naval District, Knickerbocker operated on the Hudson River and in New York Harbor as a minesweeper, tug, and dispatch ship.

Though Knickerbocker was ordered stricken from the Navy List on 14 March 1918 due to her poor material condition and accordingly was stricken on 16 March 1918, a scarcity of tugs resulted in her retention for harbor duty, and she was reinstated on the Navy List in April 1918.

Knickerbocker was decommissioned on 18 February 1919 and was sold the same day to Francis J. McDonald of Ardmore, Pennsylvania.
