USS Ranger was a sloop-of-war in the Continental Navy, serving from 1777–1780 and the first to bear her name. Built at Portsmouth Naval Shipyard on Badger's Island in Kittery, Maine, she is famed for the solo raiding campaign carried out by her first captain, John Paul Jones, during naval operations of the American Revolutionary War. In six months spent primarily in British waters, she captured five prizes, staged a single failed attack on the English mainland at Whitehaven, and caused Royal Navy ships to be dispatched against her in the Irish Sea.

The Continental Navy was the navy of the Thirteen Colonies during the American Revolutionary War. Founded on October 13, 1775, the fleet developed into a relatively substantial force throughout the Revolutionary War, owing partially to the substantial efforts of the Continental Navy's patrons within the Continental Congress. These Congressional Patrons included the likes of John Adams, who served as the Chairman of the Naval Committee until 1776, when Commodore Esek Hopkins received instruction from the Continental Congress to assume command of the force.
