The Lord of Badenoch was a magnate who ruled the lordship of Badenoch in the 13th century and early 14th century. The lordship may have been created out of the territory of the Meic Uilleim, after William Comyn, jure uxoris Earl of Buchan, Justiciar of Scotia and Warden of Moray defeated Gille Escoib MacUilleim. However, there is no evidence that the Meic Uilleim held lands in this area. After the death of John III in 1306, the lordship was taken into royal hands, although it was still claimed by his son John. The Lordship was included in the vast Earldom of Moray when it was resurrected for Thomas Randolph.
