Fiddown [2] [3] is a small village in County Kilkenny, Ireland. It is located in the south of the county, just off the N24 road, south of Kilkenny city. The village is on the banks of the River Suir, near the border with County Waterford to which the village is connected via the Fiddown Bridge.[4] Carrick-on-Suir is 7 km to the west, and Waterford city is 16 km to the east. The village is in a townland and civil parish of the same name.[2]
Fiddown was the site of a 6th-century monastery, associated with the monk Maidoc or Momodoc, which was located near the river crossing.[3]
Fiddown Island nearby is a nature reserve in the River Suir.
