Heytesbury Hundred is located very much in the centre of the county of Wiltshire, England. It is bounded on the north for a short distance by the Potterne and Cannings Hundred; it is wrapped around on the northeast and southeast by Branch and Dole Hundred; on the west it is bounded by the hundreds of Warminster and Westbury. To place the hundred within the county, see Map of the Hundreds of Wiltshire, 1832, a map from HMSO Boundary Commissioners, dated 1832, provided by A Vision of Britain through Time.
The Hundred and its individual parishes are not covered in the Victoria County History for Wiltshire
