The Sunnylvsfjorden is a fjord in Stranda and Norddal in the Møre og Romsdal county of Norway. The 26-kilometre (16 mi) long Sunnylvsfjorden is one of the innermost branches of the large Storfjorden. The fjord ranges from 600 to 2,000 metres (2,000 to 6,600 ft) wide and reaches 452 metres (1,483 ft) below sea level at its deepest point, just west of Skrenakken near the mouth of the fjord.
