Sykkylven is a municipality in Møre og Romsdal county, Norway. It is part of the Sunnmøre region. The administrative centre is the village of Aure. Other villages include Ikornnes, Straumgjerde, and Tusvik.The municipality of Sykkylven was established on 1 August 1883 when it was separated from Ørskog. The initial population was 2,029. On 1 June 1955, an area of Ørskog (population: 348) was transferred to Sykkylven.
The municipality is named after the Sykkylvsfjorden (Old Norse: Síkiflir). The first element is sík which means "small lake" or "inlet" (referring to the lake, originally probably an inlet of Fetvatnet). The last element (Old Norse: -iflir) is also found in the names Sunnylven and Vanylven and the meaning is probably "fjord". The name was written Søkelven before 1889. From 1889 until 1917, it was spelled Søkkelven, and then since 1918 it has been written Sykkylven.
