The Rahad is a river that flows in Ethiopia and eastern Sudan. The sources of this river are in Ethiopia, where it is called Shinfa, and a tributary of the Abay (Blue Nile) on the right side. The river has its origins in the Ethiopian Highlands (west of Lake Tana), from where it flows (with a total length of about ) into eastern Sudan. In Sudan, it merges into the Blue Nile.
A black-maned Sudan lion was described from this river.
