The office of High Sheriff of Dyfed was established in 1974 as part of the creation of the county of Dyfed in Wales following the Local Government Act 1972, and effectively replaced the shrievalties of the amalgamated counties of Cardiganshire, Carmarthenshire and Pembrokeshire. Since 1996 Dyfed has a purely ceremonial meaning, having been broken up for administrative purposes.
