Mountnugent, historically known as Dalysbridge (Irish: Droichead Uí Dhálaigh), is a village in southern County Cavan, Ireland. It is located on the R194 regional road on a river crossing near Lough Sheelin.
The village's more recent name of Mountnugent comes from a local branch of the Nugent family, originally an Anglo-Norman family who were cousins of Hugh de Lacy and large landowners in Meath, Cavan and Westmeath. Although the village is in County Cavan, the Roman Catholic parish of Mountnugent (or Kilbride) is in the Diocese of Meath. In the Church of Ireland, Mountnugent, or Kilbride Castlecor, is part of the parish of Castlepollard in the diocese of Meath and Kildare.
The village is in the Cavan–Monaghan constituency in the electoral division of Kilbride. For planning applications or land registration purposes, it is in the barony of Clanmahon.
While the river that the village is located on, with its mid-18th century bridge, is sometimes referred to as the Inny, most sources name a river 3 kilometers to the south west forming the boundary of Meath and Cavan near Ross Castle as the River Inny, rising near Oldcastle, and the river that flows through the village as the Mountnugent stream, rising near Ballyjamesduff.
During the launch of Ireland's new postcode system, Eircode, residents were surprised that Mountnugent was counted as part of County Meath, and that the Irish name was now a literal translation of the English name - "Sliabh an Nuinseannaigh".
It has one public house (The Bridge Inn), one grocery shop (Smiths), one fuel station (Smiths), one vehicle repair shop (Smiths), one clothes shop (Magees), two churches (Roman Catholic: St Bridget's, built c. 1820; Church of Ireland: St Bride's, built 1804) and one primary school. There is a hotel just outside the village on the shores of Lough Sheelin-Crover House Hotel. An equestrian centre is located three kilometers outside the village. The primary school (Scoil Bhríde) has about 120 children and the village population, including neighbouring townlands, is around 500.
