Thomas Levett (1594 – ca. 1655), was an Oxford-educated Lincoln's Inn barrister, judge of the Admiralty for the Northern Counties and High Sheriff of Rutland. But Levett's chief accomplishment was as antiquarian, preserving a centuries-old chartulary kept by Cluniac monks at their Pontefract, Yorkshire abbey, and then turning it over to Yorkshire medieval scholar Roger Dodsworth for publication.
