Leighlinbridge (pronounced Locklinbridge) is a small town on the River Barrow in County Carlow, Ireland. The N9 National primary route once passed through the village, which was by-passed in the 1980s. It now lies on the R705 regional road.
It covers the townlands of Leighlin (east bank of the river) and Ballyknockan (west bank). The village features narrow winding streets, grey limestone malthouses and castle ruins overlooking a 14th-century bridge across the River Barrow, reputedly one of the oldest functioning bridges in Europe. Leighlinbridge has won many environmental awards, including county winner in the National Tidy Towns Competition, first in the Barrow Awards, overall national winner in Ireland's Green Town 2000, and represented Ireland in the European "Entente Florale" competition in 2001.
