Sautso is a canyon (valley) along the river Altaelva in Finnmark county, Norway. The valley is located in Alta Municipality, just north of the border with Kautokeino Municipality. The canyon is about long and about deep, making it the largest canyon of Northern Europe. The canyon begins just downstream (north) from the Alta Power Station. The river flows down from the Finnmarksvidda plateau (elevation: ) into the canyon (elevation: ), so the walls of the canyon clearly show many sedimentary layers.
