This is a list of the High Sheriffs of the English County of Durham
In most counties the High Sheriff is the oldest secular office under the Crown. In the Palatinate of Durham the officeholder was appointed by and was accountable to the Bishop of Durham until 1836 when the Crown claimed authority. The High Sheriff was the principal law enforcement officer in the county but over the centuries most of the responsibilities associated with the post have been transferred elsewhere or are now defunct, so that its functions are now largely ceremonial. The High Sheriff changes every March.
