This is a list of High Sheriffs of Flintshire.
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. The shrievalty of Flintshire, together with that of Denbighshire, was abolished in 1974 when the county and shrievalty of Clwyd was created.
