Ny-Ålesund (formerly Brandal City) is the name of a small settlement on Svalbard. It is located northeast of the Brøgger Peninsula, on the south side of Kongsfjorden on Spitsbergen, which is the largest island on Svalbard. Ny-Ålesund is one of the world's northernmost settlements. About 30 people live here in the winter and around 130 in the summer. Coal mining was the origin of the establishment of the site in 1916. The founders and developers of the mining community Ny-Ålesund were the private owners of Kings Bay Kull Company AS: Lawyer Trygve Klausen and the fishing and Arctic shipowners Peter S. Brandal and Michael Knutsen. After a mining accident in 1929, mining under the auspices of the Ålesund Company ceased. In December 1933, the Norwegian state took over all the shares in Kings Bay Kull Company and in 1945, coal mining was restarted under state auspices, but the major mining accident in 1962 led to the closure of mining. Ny-Ålesund has been the starting point for several attempts to reach the North Pole and other Arctic expeditions, including Roald Amundsen's and Lincoln Ellsworth's voyage with the aircraft carriers N 24 and N 25 in 1925 and the airship Norway in 1926 and Umberto Nobile's voyage in 1928 with the airship Italia.

After 1964, Ny-Ålesund was built up as a center for international Arctic research and environmental monitoring. Several countries have research stations, and in the summer the research activity is great.

Ny-Ålesund has its own airport and quay. A museum shows the site's history from its establishment as a coal mining town until today as a research center. Ny-Ålesund has the world's northernmost post office, a small local café and a souvenir shop. Since its establishment in 1916, Kings Bay Kull Company has owned and operated Ny-Ålesund. The company was originally headquartered in Ålesund, hence the name Ny-Ålesund.

Ny-Ålesund has the largest collection of protected cultural monuments on Svalbard and the post office building in Ny-Ålesund was named the cultural monument of the week for week 50 of the Cultural Heritage Year 2009.
