USS Mary B. Garner (SP-682) was a United States Navy minesweeper in commission from 1917 to 1919.

Mary B. Garner was built as a commercial fishing vessel of the same name by the William E. Woodall Company at Baltimore, Maryland, in 1912. On 30 April 1917, the U.S. Navy purchased her from the Coast Fish Oil and Guano Company of Lewes, Delaware, for use during World War I. Assigned the section patrol number 682, she was commissioned on 12 May 1917 as USS Mary B. Garner (SP-682).

Assigned to the Minesweeping Squadron of the 4th Naval District and based at Philadelphia, Pennsylvania, Mary B. Garner carried out minesweeping duties in the rivers, harbors, and coastal waters of Pennsylvania, Delaware, New Jersey, and Maryland. She ran aground and was wrecked on 11 April 1918 at Prime Hook Beach, Delaware, with the loss of one life, but she was salvaged and returned to her duties for the rest of World War I.

Mary B. Garner was decommissioned at Philadelphia on 15 May 1919.
