West Connacht (; Modern Irish: Iar Connacht) was a kingdom of Gaelic Ireland, associated geographically with present day County Galway, particularly the area known more commonly today as Connemara. The kingdom represented the core homeland of the Connachta's Uí Briúin Seóla kindred and although they ruled, there were smaller groups of other Gaels in the area, such as the Delbhna Tir Dha Locha and the Conmhaícne Mara. It existed from 1051 onwards, after the Ó Conchobhair, Kings of Connacht, pushed the Ó Flaithbertaigh to the West of Lough Corrib, from their original territory of Maigh Seóla. Iar Connacht remained a subordinate túath of Connacht, until the 13th century, after which it was more independent.
