USS Plumas County (LST-1083) was an LST-542-class tank landing ship in the United States Navy.

Unlike many of her class, which received only numbers and were disposed of after World War II, she survived long enough to be named.

She was named Plumas County on 1 July 1955 and spent the rest of her career operating off California, and in the Pacific, carrying out joint amphibious exercises with Nationalist China and South Korea.

She was placed in reserve at Sasebo on 22 August 1961, and was transferred to the Military Sea Transportation Service in December 1965.
