James Chaloner (d. 1660) served as Governor of the Isle of Man from 1658 under the Commonwealth, having previously sat among the judges at the trial of Charles I. He wrote *A Short Treatise of the Isle of Man* (1656), an important early account of the Island's laws, customs, and natural history. He laid charges of financial mismanagement against William Christian (Illiam Dhone), who secretly departed the Island in June 1659, after which Chaloner sequestered his estates. Chaloner died between 2 and 30 July 1660, shortly after proclaiming Charles II on the Island.
