Roger Bigod (d. 1221), was the son of Hugh Bigod and succeeded to the earldom of Norfolk, was confirmed in his earldom and other honours by Richard I, after he had fallen under the displeasure of Henry II.

He took part in the negotiations for the release of Richard from prison, and after the king's return to England became justiciar. The earl was one of the leaders of the baronial party which obtained John's assent to Magna Carta, and his name appears among the signatories to this document.
