• River Nanny – flows east from Co. Meath; enters near Duleek.

• River Tolka – Note: The Tolka is a separate Dublin river; likely an error in original list. The River Yellow (or Ownboy) is a Boyne tributary.

The Boyne's main stem is ~112 km long. Its catchment covers ~2,695 km². Famous for the Battle of the Boyne (1690) and the Neolithic Brú na Bóinne complex (Newgrange, Knowth, Dowth).
