Connemara (in Irish: Conamara), which derives from Conmhaicne Mara (meaning: descendants of Con Mhac, of the sea), is a district in the west of Ireland comprising of a broad peninsula between Killary Harbour and Kilkieran Bay in the west of County Galway or south west Connacht. The Conmhaicne Mara were a branch of the Conmhaicne, an early tribal grouping that had a number of branches located in different parts of Connacht.
As this branch of Conmhaicne were located by the sea they became known as the Conmhaicne Mara, i.e., of the sea.
Connemara lies in the territory of Iar Connacht, "West Connacht", which is the portion of County Galway west of Lough Corrib and the portion of County Mayo in the barony of Ross.
Connemara was traditionally divided into North Connemara and South Connemara. The mountains of the Twelve Bens and the Owenglin river, which flows into the sea at An Clochán/Clifden, marked the boundary between the two parts.
Connemara is bounded on the west, south and north by the Atlantic. Connemara's land boundary with the rest of County Galway is marked by the Invermore River (which flows into the north of Kilkieran Bay), Loch Oorid, (which lies a few miles west of Maam Cross, and the western spine of the Maumturks mountains in the north of which the boundary meets the sea at the Killary a few miles west of Leenaun.
