Lillevann is a station on the Holmenkollen Line (Line 1) on the Oslo Metro. The station is located between Skogen and Voksenkollen, at an altitude of 425 m (1,394 ft) above mean sea level. The station was opened on 16 May 1916 with the extension of the line from Besserud, but the station building is older. That building was built in 1898 on an estate at Besserud, but then moved to Lillevann.
