The Sheriff of Nottinghamshire, Derbyshire and the Royal Forests is a position established by the Normans in England.
The sheriff is the oldest secular office under the Crown. Formerly the 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.
From 1068 until 1566 the position existed as Sheriff of Nottinghamshire, Derbyshire and the Royal Forests but after 1566 separate appointments were made as Sheriff of Derbyshire and Sheriff of Nottinghamshire.
