Uchtred or Uhtred, called the Bold, (d. 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.
In 995, according to Symeon of Durham, when the remains of St Cuthbert were transferred from Chester-le-Street to Durham, Uhtred went to Durham with his monks to clear the site of the new cathedral. The new cathedral was founded by Bishop Aldhun, and Uhtred married Aldhun's daughter, Ecgfrida, probably at about this time. From his marriage he received several estates that had belonged to the church.
In 1006 Malcolm II of Scotland invaded Northumbria and besieged the newly founded episcopal city of Durham. At that time the Danes were raiding southern England and King Ethelred was unable to send help to the Northumbrians. Ealdorman Waltheof was too old to fight and remained in his castle at Bamburgh. Ealdorman Ælfhelm of York also took no action. Uhtred, acting for his father, called together an army from Bernicia and Yorkshire and led it against the Scots. The result was a decisive victory for Uhtred. Local women washed the severed heads of the Scots, receiving a payment of a cow for each, and the heads were fixed on stakes to Durham's walls. Uhtred was rewarded by King Ethelred II with the ealdormanry of Bamburgh even though his father was still alive. In the meantime, Ethelred had Ealdorman Ælfhelm of York murdered, and he allowed Uhtred to succeed Ælfhelm as ealdorman of York, thus uniting northern and southern Northumbria under the house of Bamburgh. It seems likely that Ethelred did not trust the Scandinavian population of southern Northumbria and wanted an Anglo-Saxon in power there.
