Sunnmøre (English: South-Møre) is the southernmost traditional district of the western Norwegian county of Møre og Romsdal. Its main city is Ålesund. The region comprises the municipalities (Norwegian: kommuner) of Giske, Hareid, Herøy, Norddal, Sande, Skodje, Haram, Stordal, Stranda, Sula, Sykkylven, Ulstein, Vanylven, Volda, Ørskog, Ørsta, and Ålesund.
Though it is one of the three traditional districts in Møre og Romsdal, Sunnmøre is home to more than half the population of the county—with 130,601 of the 247,313 residents (53%). The district is made up of mainland as well as several large islands such as Gurskøy and Hareidlandet, plus many small islands.
While Sunnmøre has no formal administration, many national organizations chose to have separate divisions for Sunnmøre. For example, the Football Association of Norway has a separate Regional Association for Sunnmøre, separate from Nordmøre and Romsdal. This is also true for the national police.
All municipalities in Sunnmøre have adopted Nynorsk as their form of the Norwegian language, with the exception of Ålesund municipality, which has declared itself to be "neutral", though almost all of the education in Ålesund is conducted using Bokmål.
There are many local newspapers throughout Sunnmøre, as well as one that aims to cover the entire region, published from Ålesund, called Sunnmørsposten.
The major urban centres (by urban population–2013) of Sunnmøre are:
