USS Marietta (YN-101/AN-82) was a Cohoes-class net laying ship commissioned at the end of World War II.

The ship was launched on 27 April 1945; sponsored by Mrs. Theodore C. Lyster, Jr., and commissioned 22 June 1945, Lt. Richard Haber, USNR, commanding.

Following shakedown, Marietta was briefly ordered to San Francisco, California, where she spent two weeks removing the protective nets in that harbor, 14 August to 3 September 1945.

During that time she tended nets, moorings, and buoys in New York, New Jersey, Connecticut, and Rhode Island, with periodic deployment to other ports on the U.S. East Coast, including Key West, Florida, Charleston, South Carolina, Norfolk, Virginia, Boston, Massachusetts, and, Guantanamo Bay, Cuba.

Two years later preparations were started for Marietta's eventual transfer under the terms of the Military Assistance Program.
