The Røa Line (Norwegian: Røabanen) is a rapid transit line of the Oslo Metro, Norway, which runs from Majorstuen in Oslo to Østerås in Bærum. It serves neighborhoods such as Smestad, Hovseter, Huseby and Røa in northwestern Oslo, and Grini, Øvrevoll and Østerås in northeastern Bærum. The line is served by Line 2 of the metro, which connects to the city center via the Common Tunnel and onwards along the Furuset Line. The lowest part of the Røa Line, consisting of two stations, is shared with the Kolsås Line, and thus also served by Line 2 of the metro. The Røa Line is owned by Kollektivtransportproduksjon, and operated by Oslo T-banedrift on contract with the public transport agency Ruter.

The first part of the line, originally a light rail, was from Majorstuen to Smestad, and opened in 1912. It was built as a cooperation between the Municipality of Aker and the company Holmenkolbanen, and connected to the Holmenkoll Line's terminus. In 1928, the line received a connection to the city center when the first part of the Common Tunnel was completed. In 1935, the first extension of the Røa Line proper was made, when the line was extended to Røa. In 1942, the Kolsås Line became a branch. Additional extensions to the Røa Line were made in 1948 to Grini, in 1951 to Lijordet and in 1972 to Østerås. By then, the line had become an integrated part of the municipal Oslo Sporveier. The line was upgraded to rapid transit in 1995, became part of the metro and started running through the city center.
