The Tsaliet is a river in northern Ethiopia, belonging to the Nile basin. Rising in the mountains of Dogu’a Tembien, where it is first called May Leiba River and then Tinsehe River, it flows westward through a deep gorge, to become Tsaliet in its lower course, where it empties in Weri’i River, just upstream of the main Weri’i bridge along the road to Adwa.
