Irish Sea, a body of water lying between the north of Ireland and the north of England, with the south-western counties of Scotland on the north. It is connected with the Atlantic on the north-west by the North Channel and on the south by St George's Channel. Between the coasts of Louth (Ireland) and Lancaster the Irish Sea has a width of 150 miles; its greatest length north and south is about the same. Within its boundaries lie the Isle of Man and Anglesey, with Holyhead Island.
