USS Aeolus (SP-186) was the proposed name and designation for a motorboat considered for United States Navy service as a patrol vessel but never acquired. Aeolus was built in 1915 by Joe Polliot in Detroit, Michigan. The U.S. Navy inspected her for World War I service as a patrol vessel and assigned her the section patrol designation SP-186. However, the Navy never acquired her for service, and she remained in civilian hands.
