The Matthew's Range, also known as the Lenkiyio Hills, are a long mountain range in the north of Kenya that form part of the Rift Valley wall. They rise out of the dry scrub country between Lake Turkana in the north and Samburu in the south. Rising to a height of 7790ft ( 2370 Mts.).

They are capped with cedar (juniper) forests with numerous cycads, and give rise to numerous small streams, that give life to the dry country at the base. Part of the mountain range has been designated a wildlife sanctuary.
