Rognvald Eysteinsson (fl. 865) sometimes referred to with the bynames of the Wise or the Powerful was the Earl of Møre in Norway and a key figure in the founding of the Earldom of Orkney. Three quite different sources for the creation of the Norse earldom on Orkney and Shetland exist. The best known are those in the Norse Sagas but older evidence is found in the Historia Norvegiae and the Fragmentary Annals of Ireland.
