The hundreds of Cornwall (Cornish: Keverangow Kernow) were administrative divisions (hundreds) into which Cornwall, the present day county of England, in the UK, was divided between Anglo-Saxon times and the 19th century.
Some of the names of the hundreds ended with the suffix shire as in Pydarshire, East and West Wivelshire and Powdershire which were first recorded as names between 1184 and 1187. In the Cornish language the word keverang (pl. keverangow) is the equivalent for English "hundred" and the Welsh cantref. The word, in its plural form, appears in place names like Meankeverango (i.e. stone of the hundreds) in 1580 (now The Enys, north of Prussia Cove and marking the southern end of the boundary between the hundreds of Penwith and Kerrier), and Assa Govranckowe 1580, Kyver Ankou c. 1720, also on the Penwith – Kerrier border near Scorrier. It is also found in the singular form at Buscaverran, just south of Crowan churchtown and also on the Penwith-Kerrier border. The hundred of Trigg is mentioned by name during the 7th century, as "Pagus Tricurius", "land of three war hosts".
The division of Wessex into hundreds is thought to date from the reign of King Athelstan, and in the Geld Inquest of 1083, only seven hundreds are found in Cornwall, identified by the names of the chief manors of each: Connerton, Winnianton, Pawton, Tybesta, Stratton, Fawton and Rillaton (corresponding to Penwith, Kerrier, Pydar, Powder, Trigg, West Wivel and East Wivel). At the time of the Domesday Survey of 1086, the internal order of the Cornish manors in the Exeter Domesday Book is in most cases based on the hundreds to which they belonged, although the hundred names are not used.
