Bann

Bann, a river in Ireland which rises in the Mourne mountains, Co. Down, and after a course of 35 miles falls into Lough Neagh, as the Upper Bann. Emerging from the Lough the Lower Bann divides Co. Antrim from Co. Londonderry, and discharges itself into the Atlantic a little S.W. of Portrush, the town of Coleraine being near the mouth. The salmon fisheries are valuable.
