The M8 motorway (Irish: Mótarbhealach M8) is an inter-urban motorway in Ireland, which forms part of the motorway from the capital Dublin to Cork city. The 149 km motorway commences in the townland of Aghaboe, County Laois and runs through the counties of Kilkenny, Tipperary and Limerick, terminating at the Dunkettle interchange in County Cork. First called for in the Road Needs Study (1998), it was later incorporated into the National Development Plan (2000–2006) and later still formed part of the Irish Government's Transport 21 plan for infrastructural development. The majority of the M8 (115 km) was built between 2006 and 2010. On 28 May 2010, the motorway was completed and had replaced almost all of the single-carriageway N8 except for a short section of urban road in Cork City.
The route starts in the townland of Aghaboe, County Laois, at a motorway-to-motorway interchange with the M7. From here it proceeds southwards, passing under the R434 and R433 roads until it runs parallel to the single-carriageway R639 road, bypassing Abbeyleix, Durrow, Cullahill, Johnstown, Urlingford, Littleton, Horse and Jockey, Cashel, New Inn, Cahir, Skeheenarinky, Kilbeheny, Mitchelstown, Kilworth Mountain, Fermoy, Rathcormac, Watergrasshill and Glanmire.
