USS Portent (AM-106) was an Auk-class minesweeper acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing.

Portent — a metal-hulled minesweeper — was named after the word "portent", something that foreshadows a coming event. In this case, it was an appropriate name since the Portent struck a mine and was sunk not long after her commissioning.

Portent was laid down on 15 November 1941 by the Pennsylvania Shipyard, Inc., Beaumont, Texas, launched on 16 August 1942, sponsored by Mrs. Arthur L. Kline, Jr., and commissioned on 3 April 1943, Lieutenant Howard C. Plummer in command.

Portent sailed via Algiers, Louisiana, and Key West, Florida, to New York City to join a convoy to Casablanca and various North African ports on 14 May 1943. From May–November, she escorted convoys between New York City and Casablanca, Morocco. Assigned to a convoy entering the Mediterranean, she anchored outside Oran, Algeria on 22 November.
