Domen (Norwegian), Duommabávti (Northern Sami), or Tuumeni (Kven)[1] is a mountain on the Varanger Peninsula in eastern Finnmark county, Norway.

The 164-metre (538 ft) tall mountain is located near the coast between the small fishing village Kiberg and the island of Vardøya.

Domen is bare and flat-topped, with a steep slope towards the Barents Sea below.

The European route E75 highway runs along the western side of the mountain from Svartnes to Kiberg.

This sea (haf) was named after the mountain Dumbr [ˈdumbz̠] (an old form of Domen).
