CARRICK-ON-SUIR, a market town of Co. Tipperary, Ireland, in the east parliamentary division, on the north (left) bank of the Suir, 1414 m. W.N.W. from Waterford by the Waterford & Limerick line of the Great Southern & Western railway. Pop. of urban district (1901) 5406. It was formerly a walled town, and contains some ancient buildings, such as the castle, erected in 1309, formerly a seat of the dukes of Ormonde, now belonging to the Butler family, a branch of which takes the title of earl from the town. On the other side of the river, connected by a bridge of the 14th century, and another of modern erection, stands the suburb of Carrickbeg, in county Waterford, where an abbey was founded in 1336. The woollen manufactures for which the town was formerly famous are extinct. A thriving export trade is carried on in agricultural produce, condensed milk is manufactured, and slate is extensively quarried in the neighbourhood, while some coal is exported from the neighbouring fields. Dredging has improved the navigable channel of the river, which is tidal to this point and is lined with quays.
