Shannon Harbour is a small village situated on the banks of the Grand Canal in County Offaly, Ireland. The older or regional name of the village is Cluain Uaine Bheag, meaning "Clononey Beg" or "little Clononey," named in contrast to Cluain Uaine Mhor or Clononey Mor on the other side of a stream off the River Brosna. The name reflects the distance, population, and low-lying land of the area compared to its counterpart.
