Trumbert (or Tunberht or Tunbeorht) was a monk of Jarrow, a disciple of Chad and later Bishop of Hexham.

Trumbert was educated at Lastingham by Chad, and was a teacher of Bede.^[1] He was the bishop of the see of Hexham from 681 until he was deposed in 684 and was succeeded by Eata.^[2] He had previously been a monk at Ripon under Wilfrid. After his deposition, he became abbot at Gilling Abbey in north Yorkshire.^[3] He was the brother of Ceolfrith, who was abbot of Jarrow while Bede was a monk at Jarrow.^[3]
