Muotkavaara (Finnish name; Norwegian: Krokfjell;Russian: Муоткавара or Муоткаваара,Northern Sami: Muotkevárri, Inari Sami: Myetkivääri) is a hill in Lapland at the boundary between Finland, Norway and Russia. The Finnish side belongs to the Inari municipality, the Norwegian side belongs to Sør-Varanger and the Russian side belongs to Nikel. The peak (169 metres (554 ft)) is in Norway.
The Sami name (muotke, myetki) refers to an isthmus between waters.
Treriksrøysa, a rock cairn at the tripoint was erected in 1846. A concrete tetrahedron was added on the top in 1945.
The border of Norway and Russia was demarcated in 1826, while Finland was an autonomous part of Russia. Further in 1833 it was ruled that the border between Grand Duchy of Finland and Russia proper meets the Norwegian border at ”Mutkavaara” (Muotkavaara).
Between 1920 and 1944, when Petsamo was part of Finland, there was no tripoint, since Norway and Russia did not share a border. Muotkavaara became a tripoint again in 1944, when Finland ceded Petsamo to the Soviet Union in the Moscow Armistice. The border was further modified in 1947 when Finland sold the Jäniskoski area to the Soviet Union. Since then the border between Finland and Soviet Union (now Russia) is oriented to the south-west from the Muotkavaara tripoint.
The tripoint is most easily reached from Grensefoss on the Norwegian side, around 5 km hike each way.
