USS Bab (SP-116) was high-speed motorboat leased for one dollar by the U.S. Navy during World War I. She was placed in service as a patrol craft and was assigned to the vicinity of Chicago, Illinois. Post-war she was returned to her owner for the sum of one dollar.

Bab was a 38-foot section motorboat of the high-speed "sea sled" design built in 1917 at Boston, Massachusetts, by Murray and Tregurtha Company. She was leased by the Navy for $1.00 from Milton Wilson of Chicago, Illinois; and designated as a section patrol craft, SP-116; and delivered on 6 October 1917.

Assigned to the 9th Naval District, Bab patrolled the waters of Lake Michigan until the onset of winter caused her to be laid up.

Eventually judged "not suitable for naval use", Bab was returned to her owner for the sum of $1.00 on 31 December 1918.
