The title Lord Falconer of Halkerton is a dormant title in the peerage of Scotland, created on 20 December 1646 for Sir Alexander Falconer, Lord of Session, with remainder to his heirs-male whatsoever. King Charles I granted Sir Alexander a yearly pension of £200 with the title, for his ability, integrity, and affection for administration of Justice. David Hume's mother was a great-granddaughter of a brother of Sir Alexander Falconer, 1st Lord Falconer of Halkerton. In 1778, the 7th Lord inherited the Earldom of Kintore, and the two titles remained linked until 1966. The lordship then became vacant with the death of Arthur George Keith-Falconer, 12th Lord Falconer of Halkerton and 10th Earl of Kintore, although the earldom of Kintore continued in the female line. Peter Serrel Falconer (died 2003), an architect, was the presumed heir to the feudal barony (1206) and Lordship (1646) of Halkerton, and had three sons (Thomas, Richard and William), but did not pursue the claim.
