John Halsey (c. 1662–1708) was a British privateer and a later pirate who was active in the Atlantic and Indian Oceans during the early 18th century. Although much of his life and career is unknown, he is recorded in A General History of the Pyrates which states "He was brave in his Person, courteous to all his Prisoners, lived beloved, and died regretted by his own People. His Grave was made in a garden of watermelons, and fenced in with Palisades to prevent his being rooted up by wild Hogs."
