Halfshire was one of the hundred in the English county of Worcestershire. As three of the five hundreds in the county were jurisdictions exempt from the authority of the sheriff, the hundred was considered to be half what was subject to his jurisdiction, whence the name.
The hundred seems to have been formed in the mid-12th century, by amalgamating the Domesday hundreds of Came, Clent, Cresslau, and Esch, other than those parts, where an ecclesiastical exempt jurisdiction existed, which were joined to the appropriate ecclesiastical hundreds about the same time.
Anciently, it contained the following manors:
Belbroughton, Bentley Pauncefoot, Bromsgrove, Chaddesley Corbett, Churchill, Worcestershire, Church Lench, Cofton Hackett, Cradley, Doverdale, Droitwich, Dudley, Elmbridge, Elmley Lovett, Feckenham, Frankley, Hadzor, Hagley, Kidderminster, Kingsford (in Wolverley), Kings Norton, Kington, Lutley, Northfield, Oldswinford, Over Mitton (formerly in Hartlebury, but now part of Stourport), Pedmore, Rushock, Salwarpe, Stone, Stourbridge, Upton Warren, and Warley Wigorn. Of these, Kington and Church Lench were detached. Feckenham and Bentley Pauncefoot were also nearly detached until Tardebigge was added.
The following were added in the 19th century:
- Yardley from Pershore Hundred in 1760.
- Tardebigge, now Tutnall and Cobley from Warwickshire in 1844.
- Halesowen (except Warley Wigorn, Cradley and Lutley) from Shropshire in 1844.
- Clent and Broom, Worcestershire from Staffordshire in 1832.
- Upper Arley from Staffordshire 1895.
By the late 17th century the hundred was administered in two divisions. The court for the lower division met at Churchill 'under a great tree'.
