Ecgbert or Egbert (died November 766), also spelled Egberht or Ecgberht, was an 8th-century cleric who established the archdiocese of York in 735. In 737, Ecgbert's brother became king of Northumbria and the two siblings worked together on ecclesiastical issues. Ecgbert was a correspondent of Bede and Boniface and the author of a legal code for his clergy. Other works have been ascribed to him, although the attribution is doubted by modern scholars.
