The Eiksund tunnel (Norwegian: Eiksundtunnelen) is an undersea tunnel in Møre og Romsdal county, Norway, which runs under the Vartdalsfjorden connecting the municipalities of Ørsta and Ulstein. The tunnel is 7,765 metres (25,476 ft) long and reaches a depth of 287 metres (942 ft) below sea level, and was the deepest undersea tunnel in the world until Norway's Rogaland county opened its 292 m (958 ft) deep Ryfast tunnel system in December 2019.
