Humberside was an administrative county of England from 1974 until April 1, 1996. It was composed of two halves either side of the Humber estuary, created using part of Yorkshire and Lincolnshire. Its county town was Beverley, its largest city Kingston upon Hull.

It had several districts - Beverley, Boothferry, Cleethorpes, East Yorkshire, Glanford, Great Grimsby, Holderness and Scunthorpe.

It bordered North Yorkshire to the north and west, South Yorkshire and Nottinghamshire to the south-west, and Lincolnshire to the south. It faced east towards the North Sea.

At the time of its creation, there was very little connecting the two parts of the county. The addition of the northern Lincolnshire areas had been a late change, originally the plan was for it to cover the area of the current East Riding of Yorkshire and Hull. It was promised by the government that the Humber Bridge would make it a more viable unit.

This finally opened 1981, but the county was instead abolished in 1996 by The Humberside (Structural Change) Order 1995.

This resulted in four successor authorities made up as follows

• Kingston-upon-Hull
• East Riding of Yorkshire : Beverley, East Yorkshire, Holderness, and northern Boothferry
• North Lincolnshire : Glanford, Scunthorpe and southern Boothferry
• North East Lincolnshire : Great Grimsby, Cleethorpes

The office of Lord-Lieutenant of Humberside was also abolished. The Yorkshire part became the ceremonial county of the East Riding of Yorkshire (which included Hull); the Lincolnshire part reverted to Lincolnshire for ceremonial purposes.

Despite this local government reform, the term 'Humberside' has not fallen out of use as a geographic designation. There is still a Humberside Police , a Humberside Airport (roughly halfway between Scunthorpe and Grimsby), a Humberside Fire Service and BBC Radio Humberside.

Also, the whole of the former administrative county of Humberside, including the Lincolnshire parts, is part of the government office region of Yorkshire and the Humber (originally 'Yorkshire and Humberside').
