The River Nore is one of the principal rivers (along with the River Suir and River Barrow) in the South-East Region of Ireland. The 140-kilometre-long river drains approximately 2,530 square kilometres of Leinster and Munster, that encompasses parts of three counties (Tipperary, Laois, Kilkenny). Along with the River Suir and River Barrow, it is one of the constituent rivers of the group known as the Three Sisters.
