This is a list of High Sheriffs of Lincolnshire.
The High Sheriff is the oldest secular office under the Crown. Formerly 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.
Between 1974 and 1996 the shrievalty in Lincolnshire was interrupted when the County of Humberside took over the complete northern part of the county. In 1996 the northern bailiwicks reverted to Lincolnshire once more, after eight North Lincolnshire based High Sheriffs of Humberside had administered the area.
