Uhtred or Uchtred, called the Bold (died 1016), was the ealdorman of all Northumbria from 1006 to 1016, when he was assassinated. He was the son of Waltheof I, ealdorman of Bamburgh, whose ancient family had ruled from the castle of Bamburgh on the Northumbrian coast and was involved in the generations-long blood feud described in De obsessione Dunelmi.
