The East Riding of Yorkshire, or simply East Yorkshire, is a ceremonial county of England. It is located in the region of Yorkshire and the Humber. The East Riding of Yorkshire may also refer to a local government district with unitary authority status, which does not include the city of Kingston upon Hull, the largest settlement in the ceremonial county, which is a separate unitary authority. The modern East Riding of Yorkshire (both ceremonial county and unitary authority), was formed in 1996 from the northern part of the non-metropolitan county of Humberside.

The East Riding of Yorkshire may also refer to the historic riding of Yorkshire (one of three ridings alongside the North Riding and West Riding), which constituted a ceremonial and administrative county until 1974. The historic riding covered a larger area than the modern county: it included some areas now in North Yorkshire, but did not include the area of Goole, which was then in the West Riding.

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. Archaeological investigations have revealed artefacts and structures from all historical periods since the last ice age. There are few large settlements and no industrial centres. The area is administered from the ancient market and ecclesiastical town of Beverley. Christianity is the religion with the largest following in the area and there is a higher than average percentage of retired people in residence.

The economy is mainly based on agriculture and this, along with tourism, has contributed to the rural and seaside character of the Riding. These aspects are also reflected in the places of interest to visitors and major landmarks, which include historic buildings, nature reserves and the Yorkshire Wolds Way long-distance footpath. The open and maritime aspects and lack of major urban developments have also led to the county being allocated relatively high targets for the generation of energy from renewable sources.

Major sporting and entertainment venues are concentrated in Kingston upon Hull, while the seaside and market towns support semi-professional and amateur sports clubs and provide seasonal entertainment for visitors. Bishop Burton is the site of an agricultural college, and Hull provides the region's only university. On the southern border, close to Hull, the Humber Bridge spans the Humber Estuary to enable the A15 to link Hessle with Barton-upon-Humber in North Lincolnshire.

It is believed by many archaeologists that the Wolds of East Yorkshire were the first part of Britain the be settled by what they call the "Beaker People".
