USS Gypsum Queen (SP-430) was a tugboat acquired by the United States Navy during World War I. She was assigned to the French coast as a minesweeper, as well as a tugboat to provide assistance to disabled Allied ships. Performing this dangerous work, Gypsum Queen struck a rock near Brest, France, and sunk, sending 15 crew members to their deaths.

Gypsum Queen — a sea-going tug — was built by Dialogue & Company, Camden, New Jersey in 1890, acquired from her owners, J. B. King Transportation Co. of New York City in September 1917; and commissioned on 4 December 1917 at New York City.

Turned over to the 3d Naval District, Gypsum Queen was fitted out for overseas service at New York Navy Yard and subsequently served in French ports as a towing vessel and a minesweeper.

While returning from rendering assistance to minesweepers foundering off the coast of France, Gypsum Queen struck a rock near Armen Light House off Brest on 28 April 1919 and sank with a loss of two officers and 13 men.
