Ulrikken Tunnel or Ulrikkentunnelen is a railway tunnel on Bergensbanen in Norway that runs between Bergen Railway Station and Arna Station. The 7,670 meter long tunnel runs under the northern part of the mountain Ulriken in Bergen. Before the tunnel was opened in 1964, Bergensbanen went via Nesttun. This stretch is now a heritage railway, Gamle Vossebanen. The tunnel has single track and is electrified. Jernbaneverket has plans for building a second track through the mountain.
