Unofficial flag of Nottinghamshire county, England

Nottinghamshire (/ˈnɒtɪŋəmʃər, -ʃɪər/;[4] abbreviated Notts.) is a ceremonial county in the East Midlands of England. The county is bordered by South Yorkshire to the north-west, Lincolnshire to the east, Leicestershire to the south, and Derbyshire to the west. The largest settlement is the city of Nottingham (323,632), which is also the county town. The county has an area of 2,160 km2 (830 sq mi) and a population of 1,154,195. The latter is concentrated in the Nottingham built-up area in the south-west, which extends into Derbyshire and has a population of 729,997. The north-east of the county is more rural, and contains the towns of Worksop (44,733) and Newark-on-Trent (27,700). For local government purposes Nottinghamshire comprises a non-metropolitan county, with seven districts, and the Nottingham unitary authority area. The East Midlands Combined County Authority includes Nottinghamshire County Council and Nottingham City Council. The geography of Nottinghamshire is largely defined by the River Trent, which forms a wide valley which crosses the county from the south-west to the north-east. North of this, in the centre of the county, is Sherwood Forest, the remnant of a large ancient woodland.
