The USCGC North Star was a United States Coast Guard Cutter during the Second World War.

[3] Although the United States was not yet at war, the Navy was providing convoy escorts to protect American shipping in the North Atlantic from attacks by German U-boats.

The Northeast Greenland Patrol, was organized at Boston and consisted of Coast Guard cutters Northland and the venerable Bear, as well as the North Star.

The duties of the Greenland Patrol were varied - protecting convoy routes; ice breaking and passages were found through it for the Greenland convoys; escorting merchant ship; rescuing survivors of submarine attacks; construction and maintenance of aids to navigation; reporting of weather and ice conditions; and conducting air and surface patrols.

With the official entry of the United States into the war on 8 December 1941, North Star continued her service with the Greenland Patrol.
