Thomas of Brotherton, 1st Earl of Norfolk, English politician, Lord Marshal of England (died 1338)

Thomas of Brotherton, 1st Earl of Norfolk, was the fifth son of King Edward I of England (1239–1307), and the eldest child by his second wife, Margaret of France, the daughter of King Philip III of France. He was, therefore, a younger half-brother of King Edward II and a full brother of Edmund of Woodstock, 1st Earl of Kent. He occupied the office of Earl Marshal of England.

Earl Marshal is a hereditary royal officeholder and chivalric title under the sovereign of the United Kingdom used in England. He is the eighth of the great officers of State in the United Kingdom, ranking beneath the Lord High Constable of England and above the Lord High Admiral. The dukes of Norfolk have held the office since 1672.
