Ecgberht (died 873) was king of Northumbria in the middle of the 9th century.
He first appears following the death of kings Ælla and Osberht in battle against the Vikings of the Great Heathen Army at York on 21 March 867.
Symeon of Durham records:Nearly all the Northumbrians were routed and destroyed, the two kings being slain; the survivors made peace with the pagans.
[1]Historians presume that Ecgberht ruled as the Great Army's tax collector and that he belonged to one of the several competing royal families in Northumbria.
[2] The next report of Ecgberht is in 872: "The Northumbrians expelled their king Egbert, and their Archbishop Wulfhere".
