The N23 road is a national primary road in Ireland, and is located entirely in County Kerry. The route is one of the shorter national primary routes, merely forming a link road between the N21 Limerick – Tralee route at Castleisland to the N22 Tralee – Killarney – Cork route at Farranfore. This facilitates traffic passing in the Limerick – Killarney direction or vice versa, allowing it to avoid detouring into Tralee.
