Vartdalsfjorden is a fjord in Møre og Romsdal county, Norway. It begins at the Storfjorden and Sulafjorden in the northeast and flows through the municipalities of Hareid and Ulstein on the northern shore of the fjord and through the municipalities of Ørsta and Volda on the southern shore. The 20-kilometre (12 mi) long fjord has one road crossing, the Eiksund Tunnel. The deepest part of the fjord reaches 365 metres (1,198 ft) below sea level. The village of Vartdal lies on the southern shore of the fjord in Ørsta. From 1895 until 1964, the southern banks of the fjord were part of the municipality of Vartdal.
