Baron Kingsale is a title in the Peerage of Ireland. It is the premier baron in the Irish peerage. It dates to the thirteenth century, perhaps being created c. 1223, though other sources give different dates. The first creation was by writ. The title was officially confirmed by letters patent in 1397. The numbering of the barons varies, some sources including the holders of the ancient barony, others commencing with the barons confirmed by letters patent.
