The Eikefet Tunnel (Norwegian: Eikefettunnelen) is a road tunnel in Alver Municipality in Vestland county, Norway.

The 4,910-metre (3.05 mi) tunnel is part of the European route E39 highway through the mountain Kjellrusen from the village of Eikefet to Odnåstjørni.

[1] When it opened, it was Norway's longest road tunnel.

[2] Eikefet has rated poorly in safety testing by the European Tunnel Assessment Programme.

This is due to long distances between emergency pull off areas and emergency phones; poor lighting; few escape routes; poor fire safety; and lanes that are only 3 metres (9.8 ft) wide.
