This article lists some of the attested Gaelic kingdoms of Early Medieval Ireland prior to the Norman invasion of 1169-72. For much of this period, the island was divided into numerous clan territories and kingdoms (known as túatha). These túatha often competed for control of resources and thus they continually grew and shrank (in both size and number). In addition to kingdoms or túatha, Gaelic Ireland was also divided into five prime overkingdoms (Old Irish cóiceda, Modern Irish cúige). These were Ulaid (in the north), Connacht (in the west), Laighin (in the southeast), Mumhan (in the south) and Mide (in the centre).
