The N20 road is a national primary road in Ireland, connecting the cities of Cork and Limerick. Buttevant, Croom, Charleville, Mallow and Blarney are major towns along the route. A short section of the route (from Limerick to Patrickswell) is motorway standard and is designated as the M20 Motorway.

The route starts at junction 1 at the Rosbrien interchange (south of Limerick city) where it connects to the M7 and the N18 which together form the Limerick Southern Ring Road. The route continues from this interchange as motorway (see thumbnail). This route was redesignated as motorway in August 2009. The route bypasses Dooradoyle and Raheen, through which the old N20 route used to run until the early 2000s. Interchanges and link roads connect to these locations. Two further interchanges are located on the motorway, at either end of Patrickswell. At the latter, the N20 route leaves the main road (which continues as the N21 to Tralee), i.e. one must diverge from the motorway to stay on the N20.
