The S postcode area, also known as the Sheffield postcode area, is a group of postcode districts in England, which are subdivisions of eight post towns. These cover most of South Yorkshire (including Sheffield, Barnsley, Rotherham and Mexborough), parts of north Derbyshire (including Chesterfield, Dronfield and the Hope Valley) and north-west Nottinghamshire (including Worksop), plus a small part of West Yorkshire. The S postcode area is one of six with a population above 1 million.

Three postcode districts were split and separated into ten new postcode districts. These were: The S64 district covering the Mexborough post town was originally earmarked for use as DN13, which has never been used.
