Ødevatnet (Norwegian) or Evettijärvi (Kven) is a lake located in Sør-Varanger Municipality in Finnmark county, Norway. The 2.83-square-kilometre (1.09 sq mi) lake lies entirely within Øvre Pasvik National Park, to the southeast of the large lake Ellenvatnet. Unlike some other lakes in the area, it lies in a deep fault, giving it a long and narrow profile. The fault continues northeastwards, creating the Revsaksskaret cliff.
