The Battle of Tuiteam Tarbhach (Scottish Gaelic: "plentiful slaughter"; also known as Tuttim–Tarwach, Tuttim–Turwigh, Tuttim–Tarwigh or Tutim Tarvach) was a Scottish clan battle in which the Mackays wiped out raiders from the Clan MacLeod of Lewis who were returning from an attack on Mackay land in Strathnaver. The Mackays caught up with the raiders on the north bank of the River Oykel some three miles west of where the river joins the River Cassley at the head of the Kyle of Sutherland. The battle probably took place in 1406, but the date is uncertain from the manuscripts.
