The Abbey River (Irish: Abhainn na Mainistreach) is a distributary arm of the River Shannon that flows around the northeastern, eastern, and southern shores of King's Island, Limerick before rejoining the Shannon at Hellsgate Island. Hellsgate Island is only visible at low tide. It is bridged by the Abbey Bridge, Baals Bridge, the Canal Bridge, Matthew Bridge, O'Dwyer Bridge, and the Sylvester O'Halloran Footbridge.
