Cornelis Corneliszoon Jol (1597 – 31 October 1641), nicknamed Houtebeen ("pegleg"), was a 17th-century Dutch corsair and admiral in the Dutch West India Company during the Eighty Years' War between Spain and the Dutch Republic. He was one of several early buccaneers to attack Campeche, looting the settlement in 1633, and was active against the Spanish in the Spanish Main and throughout the Caribbean during the 1630s and 40s.
