Ballyfinboy River

The Ballyfinboy River rises close to Moneygall in County Offaly, Ireland and flows in a generally northwesterly direction into Lough Derg at Drominagh. It forms part of the boundary between County Tipperary and County Offaly. The river flows through the towns of Cloughjordan and Borrisokane west of which it flows past Ballyfinboy Castle, a ruined tower house with a Sheela na gig in the townland of Ballyfinboy.
