John Hazelwood (1726 – March 1, 1800) served as a Commodore in the Pennsylvania Navy and Continental Navy and was among the most noted naval officers during the American Revolutionary War. Born in England about 1726, he became a mariner and settled in Philadelphia early in life, became married and had several children. Promoted to Commodore during the Philadelphia campaign, he also became commander of Fort Mifflin while it was under siege by the British. Throughout the campaign Hazelwood and General Washington were in frequent communication with letters. During the weeks spent engaging the British navy on the Delaware River Hazelwood innovated many naval tactics, kept the British navy at bay for weeks and played a major role in the development of riverine warfare for the American navies.
