The Crovan dynasty, from the late 11th century to the mid 13th century, was the ruling family of an insular kingdom known variously in secondary sources as the Kingdom of Mann, the Kingdom of the Isles, and the Kingdom of Mann and the Isles. The eponymous founder of the dynasty was Godred Crovan, who appeared from obscurity in the late 11th century, before his takeover of the Isle of Man and Dublin. The dynasty was of Gaelic-Scandinavian origin, descending from a branch of the Uí Ímair, a dominant kindred in the Irish Sea region which first appears on record in the late 9th century.
