USS Grackle (AM-73) was a minesweeper in the service of the United States Navy during World War II.

Grackle was laid down on 6 June 1929 as MV Notre Dame by the Bath Iron Works Corp. of Bath, Maine, for F. J. O'Hara and Sons, Inc. of Boston, Massachusetts.

Acquired by the Navy on 16 September 1940, her conversion to a minesweeper began on 1 October 1940 at the Bethlehem Steel Co. of East Boston, Massachusetts.

Following shakedown out of Yorktown, Virginia, and Newport, Rhode Island, USS Grackle departed Portland, Maine on 25 September 1941 for service in Newfoundland as a unit of Minesweeper Division 25, Squadron 9 of the Atlantic Fleet.

Reaching Argentia, Newfoundland on 2 October, Grackle conducted minesweeping patrols from that port until 15 January 1942, and following repairs at Boston, Massachusetts she returned to sweeping duties at Argentia until the spring of 1944.
