Vettakollen is a hill and neighbourhood in the borough of Vestre Aker in Oslo, Norway.
The hill lies west of Sognsvann and southeast of VoksenÃÂ¥sen and Holmenkollen, and measures 419 metres above mean sea level. The estimated population in the Vettakollen area is 7 600 people. The built-up residential area south of the hill is served by the Oslo Metro station Vettakollen, GullerÃÂ¥sen, GrÃÂ¥kammen and SkÃÂ¥dalen.
The name stems from the beacon hill's former use as the site of a beacon (). Before modern times, such beacons were set alight on a series of hills to constitute an alarm system. The naming is found in other hills, such as VardÃÂ¥sen, Varingskollen and probably Brannfjell.
