Roger Bigod (c. 1144/1150 – 1221) was the son of Hugh Bigod, 1st Earl of Norfolk and his first wife, Juliana de Vere. Although his father died 1176 or 1177, Roger did not succeed to the earldom of Norfolk until 1189 for his claim had been disputed by his stepmother for her sons by Earl Hugh in the reign of Henry II. King Richard I confirmed him in his earldom and other honours, and also sent him as an ambassador to France in the same year. Roger inherited his father's office as royal steward. He took part in the negotiations for the release of Richard from prison, and after the king's return to England became a justiciar.
