Cináed mac Ailpín (Modern Gaelic: Coinneach mac Ailpein), commonly anglicised as Kenneth MacAlpin and known in most modern regnal lists as Kenneth I (810 – 13 February 858), was a king of the Picts who, according to national myth, was the first king of Scots. He was thus later known by the posthumous nickname of An Ferbasach, "The Conqueror". The dynasty that ruled Scotland for much of the medieval period claimed descent from him.
