USS Spadefish (hull number SS/AGSS-411) was a Balao-class submarine, the first ship of the United States Navy to be named for the spadefish.

Although she was commissioned late in the war and spent only one year in the Pacific war zone, she was able to run up a record of 88,091 tons in 21 ships and numerous trawlers sunk. Decommissioned in 1946, Spadefish was struck from the naval register in 1967 and sold for scrap in 1969.
