Selly Oak is an industrial and residential area in south-west Birmingham, England. The area gives its name to Selly Oak ward and includes the neighbourhoods of: Bournbrook, Selly Park, and Ten Acres. The adjoining wards of Edgbaston and Harborne are to the north of the Bourn Brook, which was the former county boundary, and to the south are Weoley, and Bournville. A district committee serves the four wards of Selly Oak, Billesley, Bournville and Brandwood. The same wards form the Birmingham Selly Oak constituency, represented since 2010 by Steve McCabe (Labour). Selly Oak is connected to Birmingham by the Pershore Road (A441) and the Bristol Road (A38). The Worcester and Birmingham Canal and the Birmingham Cross-City Railway Line run across the Local District Centre.

Bournbrook is an industrial and residential district in southwest Birmingham, England, in the ward of Bournbrook and Selly Park and the parliamentary constituency of Birmingham Selly Oak. Before 2018 it was in Selly Oak Council Ward. Prior to what is commonly termed the Greater Birmingham Act, which came into effect on 9 November 1911, the Bourn Brook watercourse was the North Eastern boundary of Worcestershire, and the area was locally governed by the King's Norton and Northfield Urban District Council.
