USS Carlotta (SP-1785) was a United States Navy patrol vessel in service from 1917 to 1918.
Carlotta was built as a civilian motorboat of the same name. In August 1917, the U.S. Navy obtained her from her owner, the Commonwealth of Virginia, for use as a section patrol boat during World War I. She was placed in service as USS Carlotta (SP-1785).
Assigned to the 5th Naval District, Carlotta performed patrol duty at Cape Charles and radio inspection duty at Newport News, Virginia, for the rest of World War I.
The Navy returned Carlotta to the Commonwealth of Virginia in October 1918.
