USS Confederacy was a 36-gun sailing frigate of the Continental Navy in the American Revolutionary War.

She was launched on 8 November 1778 at Chatham (Norwich), Connecticut, and towed to New London to be prepared for sea.

On 17 September 1779 Confederacy was ordered to carry the French Minister and his family back to France.

Later John Jay, the first American Minister to Spain, his secretary, and family were added to the passenger list.

During the passage on 7 November 1779 Confederacy was completely dismasted and almost lost, but managed through the skillful seamanship of Captain Harding to reach Martinique early in December.
