Earl of Kintore is a title in the Peerage of Scotland. It was created in 1677 for Sir John Keith, third son of William Keith, 6th Hereditary Earl Marischal of Scotland and Chief of Clan Keith. He was made Lord Keith of Inverurie and Keith Hall at the same time, also in the Peerage of Scotland. At the death of William, the 4th Earl, in 1761, the Earldom and Lordship became dormant, as no-one could prove a claim to them. In 1778, it was decided that the Earldom, Lordship and Chieftaincy of Clan should pass to Anthony Adrian Falconer, Lord Falconer of Halkerton, who changed his surname to Keith-Falconer. The Lordship Falconer of Halkerton and the Earldom of Kintore and Lordship Keith of Inverurie and Keith Hall remained united until 1966, when, at the death of the 10th Earl, the Lordship Falconer of Halkerton became dormant.

The title of Earl Marischal was created in the Peerage of Scotland for William Keith, the Great Marischal of Scotland.
