The Honour of Clitheroe (also spelled Honor) is an ancient grouping of manors and royal forests centred on Clitheroe Castle in Lancashire, England; an honour traditionally being the grant of a large landholding complex, not all of whose parts are contiguous. In the case of Clitheroe, this complex was loosely clustered around the ancient wapentake of Blackburnshire.
Before the Norman Conquest, the lands of Blackburnshire were held by Edward the Confessor, while Bowland was held by Tostig, son of Godwin, Earl of Wessex. In 1092, Roger de Poitou acquired a large part of what is now Lancashire, including the hundred of Blackburnshire.
By the end of the 11th century, Poitou's landholdings had been confiscated and came into the possession of the De Lacys, Barons of Pontefract and Lords of Bowland. In 1102, Henry I granted the fee of Blackburnshire and further holdings in Hornby, and the vills of Chipping, Aighton and Dutton in Amounderness to Robert de Lacy, 2nd Baron of Pontefract, while confirming his possession of Bowland. These lands formed the basis of what became known as the Honour of Clitheroe.
