The Kleiver Tunnell (Norwegian: Kleivertunnelen) is a 3.670-kilometer (2.280 mi) railway tunnel in Larvik, Norway. The tunnel carries for the most part two tracks of the Vestfold Line and is dimensioned for speeds up to 250 km/h (160 mph).

Construction started in 2013 and the tunnel opened on 24 September 2018 as part of the Farriseidet–Porsgrunn project. The tunnel is designed so it can be extended towards Larvik when a new railway route through Larvik has been designed upon. The eastern 800 meters (2,600 ft) of the tunnel are therefore single track and lack a high-speed profile, while the rest of the tunnel is double track. Once the tunnel has been extended, the single-track section will then be converted to an emergency exit.
