Degory Priest (c. 1579 – c. 1621) was a member of the Leiden contingent on the historic 1620 voyage of the ship Mayflower. He was a hat maker from London who married Sarah, sister of Pilgrim Isaac Allerton in Leiden. He was a signatory to the Mayflower Compact in November 1620 and died less than two months later. In some documents of the time, his name was also written as Digory Priest.
