Northern England, also known as the North of England, the North or the North Country, is a cultural region of England. It is not an official government region, but rather an informal amalgamation of counties. The southern extent of the region is roughly the River Trent, while the North is bordered by Scotland.

Northern England comprises three regions of England - the North East, North West and Yorkshire and the Humber. The counties of Northern England combined have a population of around 14.5 million covering an area of 37,331 km² (14,414 sq mi).

During antiquity most of the area was part of Brigantia — homeland of the Brigantes and the largest Brythonic kingdom of Great Britain. After the Roman conquest of Britain the city of York became capital of the area, called Britannia Inferior then Britannia Secunda. In Sub-Roman Britain new Brythonic kingdoms of the Hen Ogledd emerged. The Angle settlers created Bernicia and Deira from which came Northumbria and a Golden Age in cultural, scholarly and monastic activity, centred around Lindisfarne and aided by Irish monks.Norse and Gaelic Viking raiders gained control of much of the area, creating the Danelaw. During this time there were close relations with Mann and the Isles, Dublin and Norway. Northumbria was unified with the rest of England under Eadred around 952.

England ⁱ/ˈɪŋɡlənd/ is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west; the Irish Sea is to the north west, the Celtic Sea to the south west, while the North Sea to the east and the English Channel to the south separate it from continental Europe. Most of England comprises the central and southern part of the island of Great Britain in the North Atlantic. The country also includes over 100 smaller islands such as the Isles of Scilly and the Isle of Wight.

The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but it takes its name from the Angles, one of the Germanic tribes who settled during the 5th and 6th centuries. England became a unified state in AD 927, and since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world. The English language, the Anglican Church, and English law—the basis for the common law legal systems of many other countries around the world—developed in England, and the country's parliamentary system of government has been widely adopted by other nations. The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation. England's Royal Society laid the foundations of modern experimental science.
