Eadnoth the Constable (died 1068) also known as Eadnoth the Staller, was an Anglo-Saxon landowner and steward to Edward the Confessor and King Harold II. He is mentioned in Domesday Book as holding thirty manors in Devon, Dorset, Somerset, and Wiltshire, before the Norman conquest. He may have been the same man as Eadnoth of Ugford, also known as Alnoth.Eadnoth was killed at Bleadon in 1068, leading a force against the two sons of Harold II, who had invaded Somerset. His son Harding became sheriff reeve of Bristol, and one of his grandsons was Robert Fitzharding, the ancestor of the Berkeley family of Berkeley Castle.
The vast majority of his estate, worth £100 or more, was used for the endowment of the future earldom of Chester. At least six manors, however, were acquired by his son, Harding son of Eadnoth, ancestor of the Fitz Harding family of Bristol, future lords of the great honour and castle of Berkeley. The present Lord Berkeley is himself a very distant descendant and still sits in the House of Lords as a life peer, under the title Lord Gueterbock.
