USS Specter (AM-306) was an Admirable-class minesweeper built for the United States Navy during World War II.

Initially named Spector, the ship was laid down on 5 September 1943 by Associated Shipbuilders, Seattle, Washington; launched on 15 February 1944, sponsored by Miss Carol D. Petrie, and commissioned on 30 August 1944.

After stops at Eniwetok and Tinian, Specter arrived at Iwo Jima on 16 February, three days before the landing, and began minesweeping operations.

During this period, she conducted antisubmarine patrols, swept mines off Okinawa and Iheya Shima, and made two open-sea sweeps in the East China Sea.

She sailed for Japan on 28 August and, after touching at Buckner Bay, Okinawa, arrived in Japanese home waters on 9 September.

On 11 December 1945, Specter was ordered home; she arrived at San Diego on 11 January 1946; and was routed onward to Orange, Texas, where she was placed in reserve, out of commission later in the year.
