Erdington is a suburb and ward of Birmingham in the West Midlands County, England. Historically part of Warwickshire, it is located 5 miles (8 km) northeast of central Birmingham, bordering Sutton Coldfield. It was also a council constituency, managed by its own district committee. The former council district consisted of the ward of Erdington as well as Tyburn, Stockland Green and Kingstanding, although all of Kingstanding and most of both Tyburn and Stockland Green wards lie outside the historical boundaries of Erdington. Stockland Green was formerly part of Aston, Kingstanding part of Perry Barr, and Tyburn partially split between Aston and Hodge Hill. Erdington (ward) was part of the Sutton Coldfield constituency before 1974.
