Sognsvann is a rapid transit station of the Oslo Metro's Sognsvann Line. It is situated Kringsjå neighborhood of the Oslo, Norway, borough of Nordre Aker. Located 8.7 kilometers (5.4 mi) from Stortinget, the station is served by Line 5 of the metro every fifteen minutes. Travel time to Stortinget is sixteen minutes.

The station opened on 10 October 1934 at the same times as the rest of the Sognsvann Line. The station received a major upgrade in 1993, in which it received longer platforms. The new station was designed by Arne Henriksen. The station is located next to and serves the Norwegian School of Sport Sciences and the National Archives of Norway, as well as the recreational area around the lake of Sognsvann.

The station was built as the original terminus of the Sognsvann Line. Construction started in 1933 and the station and line opened on 10 October 1934. The area around the station was originally a recreational area around the lake Sognsvann. At the station there were two cafés, which were demolished in the 1960s to allow for new developments. For decades the station was mostly used to reach recreational areas. The Norwegian School of Sport Sciences took its new campus next to the station into use in 1968, followed by the National Archives in 1978.

During the 1980s, the city decided to connect the four suburban lines west of the city center with the Oslo Metro. The Sognsvann Line was selected as the first line to be upgraded, so the two systems would become compatible. The line was upgraded to metro standard by replacing the overhead wire with a third-rail power supply and installing automatic train protection. For Sognsvann this also meant that the single track was replaced with a double track. From 4 April 1993 trains along the Sognsvann Line were connected to the eastern part of the metro, initially connected with the Østensjø Line.
