Bertram de Crioill was a mid-13th-century Englishman who served as Lord Warden of the Cinque Ports.
He was the son of John and Margery Criol.
Virtually nothing is known about him or his appointment as Lord Warden of the Cinque Ports, but the Patent Rolls of Henry III for the year 1250 record a "Grant to Bertram de Crioill of the residue of the waste and the wardship of the land late of John de Bendenges from 17 June this year until the full age of Thomas son and heir of Peter de Bendenges saving to the king the lands which the said John held in chief."
He left two sons, John and Nicholas.
