River Sgitheach also known as Skiach or Skiack, is a river in Ross and Cromarty, Scotland. It rises on the southern slopes of Ben Wyvis, passes through Strath Sgitheach, passing Clare plantation, Swordale, the village of Evanton, and after about 13 miles (21 km) empties into the Cromarty Firth near the ruin of the old Kiltearn parish church. About a mile to the northeast, on the other side of Balconie Point, the Allt Graad also empties in the Firth. The ruin that lies on the beach between the two rivers is an old salmon fishing bothy of the Novar Estate.
