USS Navajo (AT-64) was an oceangoing tugboat in the United States Navy, and the lead ship of its class. It was named for the Navajo people. Originally called the Navajo-class of fleet tugs, it was later renamed the Cherokee-class after loss of the first two ships of the class. Navajo was laid down by the Bethlehem Shipbuilding Corporation, Staten Island, New York, on 12 December 1938; launched on 17 August 1939, sponsored by Miss Olive Rasmussen; and commissioned on 26 January 1940. The tug was sunk by a Japanese submarine in 1943.
