Baltimore is a village in western County Cork, Ireland. It is the main village in the parish of Rath and the Islands, the southernmost parish in Ireland. It is the main ferry port to Sherkin Island, Cape Clear Island and the eastern side of Roaring Water Bay (Loch Trasna) and Carbery's Hundred Isles.
Although the name Baltimore is an anglicisation of the Irish meaning "town of the big house", the Irish-language name for Baltimore is that of the O'Driscoll castle, Dún na Séad or Dunashad ("fort of the jewels"). The recently restored castle is open to the public and overlooks the town.
