Slieverue (Sliabh Rua or Red Mountain in Irish) is a parish in County Kilkenny, Ireland. It is located to the north of Waterford Harbour, where the rivers Barrow and Suir come together. Despite the name, the land is relatively low-lying and fertile. The village of Slieverue is located alongside the main N25 road to New Ross and is approximately three kilometres (two miles) away from the city of Waterford. The Church of the Assumption, a nineteenth century Roman Catholic church in Slieverue village, is the only church in the parish. A prominent hill known as Carriganurra, features a large concrete cross at its summit. Slieverue parish is home to Belview Port, the main sea port of Waterford. There are two national schools in the parish: Slieverue and Ringville. Slieverue is the birthplace of John O'Donovan (1809-1861) an Irish scholar who translated the ancient text Annals of the Four Masters into English.
