The Mormaer or Earl of Atholl was the title of the holder of a medieval comital lordship straddling the highland province of Atholl (Ath Fodhla), now in northern Perthshire. Atholl is a special Mormaerdom, because a King of Atholl is reported from the Pictish period. The only other two Pictish kingdoms to be known from contemporary sources are Fortriu and Circinn. Indeed, the early 13th century document known to modern scholars as the de Situ Albanie repeats the claim that Atholl was an ancient Pictish kingdom. In the 11th century, the famous Crínán of Dunkeld may have performed the role of Mormaer.
