The East Riding of Yorkshire, or simply East Yorkshire, is a local government district with unitary authority status, and a ceremonial county of England. For ceremonial purposes the county also includes the city of Kingston upon Hull, which is a separate unitary authority. It is named after the historic East Riding of Yorkshire (one of three ridings alongside the North Riding and West Riding), which also constituted a ceremonial and administrative county until 1974. From 1974 to 1996 the area of the modern East Riding of Yorkshire constituted the northern part of the non-metropolitan county of Humberside.
The landscape consists of a crescent of low chalk hills, the Yorkshire Wolds, surrounded by the low lying fertile plains of Holderness and the Vale of York. The Humber Estuary and North Sea mark its southern and eastern limits.
