Torsken (Northern Sami: Doaskku suohkan) is a former municipality that was located on the western coast of the large island of Senja in Troms county, Norway.

On 1 January 1964, the Rødsand area of Torsken (population: 160) was transferred to the neighboring Tranøy Municipality.

The new municipality would encompass the whole island of Senja plus part of the mainland located between the Gisundet strait and the Malangen fjord.

The official blazon is "Sable, a cross moline Or" (Norwegian: I svart et gull ankerkors).

This means the arms have a black field (background) and the charge is a cross moline (Norwegian: ankerkors; lit.

The cross moline has a tincture of Or which means it is commonly colored yellow, but if it is made out of metal, then gold is used.

The road from the northern part of the municipality to Kaldfarnes, Grunnfarnes, and Flakstadvåg was far from direct.

The municipal council (Kommunestyre) of Torsken was made up of 15 representatives that were elected to four year terms.

Here is a list of people who have held this position: Torsken was a rugged area along the west coast of the island of Senja.

Many different fjords cut into its mountainous coastline including Sifjorden, Selfjorden, Torskefjorden, Gryllefjorden, and Skipsfjorden.

Between mountain peaks that ranged from 600 to 1,000 metres (2,000 to 3,300 ft), there were deep valleys and narrow depressions.
