Boyne, a river of Ireland, which, rising in the Bog of Allen, near Carbery, in Kildare, flows through that county, King's county, Meath, and Louth, and enters the Irish Sea. It is navigable for barges up to about nineteen miles from its mouth, and for heavier craft as far as Drogheda, which is four miles up the river. Near this town is an obelisk marking the scene of the celebrated battle of the Boyne, fought in 1690. The chief affluents of the Boyne are the Mattock and the Blackwater.
