Hallamshire (or Hallam) is the historical name for an area of South Yorkshire, England, approximating to the current City of Sheffield local government area.
The origin of the name is uncertain. The English Place-Name Society describe "Hallam" originating from a formation meaning "on the rocks". Alternative theories are that it is derived from halgh meaning an area of land at a border,[1] Old Norse hallr meaning a slope or hill, or Old English heall meaning a hall or mansion.[2]
The exact boundaries of this historic district are unknown, but it is thought to have covered the parishes of Sheffield, Ecclesfield, and Bradfield—an area roughly equivalent to those parts of the present-day borough of the City of Sheffield that lie to the west of the rivers Don and Sheaf that are within the boundaries of the ancient county of Yorkshire (later descriptions also include Brightside and the parish of Handsworth).[3]
