USS Patrol was a United States Navy patrol vessel in commission from 1918 to 1919.
Patrol was a wooden-hulled vessel built for the United States Coast Guard at City Island, New York. She was commissioned as the Coast Guard cutter USCGC Patrol on 24 April 1917. She served in New York Harbor.
The U.S. Navy purchased Patrol from the Coast Guard on 11 April 1918 and soon commissioned her for service in World War I as the patrol boat USS Patrol.
In Navy service Patrol remained at New York City, operating in the section patrol under the control of the 3rd Naval District for the remainder of World War I. She was returned to the Coast Guard on 28 August 1919.

Once again in Coast Guard commission as USCGC Patrol, she remained at New York City until 1923, when she was transferred to Washington, D.C. She returned to New York in the 1930s, was renamed USCGC AB-38 in 1938, and was decommissioned in 1940.
