Tysfjord (Norwegian) or Divtasvuodna (Lule Sami)[5][6] is a former municipality in Nordland county, Norway.

Other villages in Tysfjord included Drag, Hundholmen, Korsnes, Musken, Rørvika, Skarberget, and Storå.

[10][11] The municipality (originally the parish) is named after the local Tysfjorden since it was a central geographical feature in the area.

One thought is that the first element was the old name for the fjord Þýtir which may have come from the verb þjóta which means "blowing" (as in wind) or "rushing".

[14] On 7 October 2011, the national government approved a resolution to add a co-equal, official Lule Sami name for the municipality: Divtasvuodna.

It is called Divtasvuodna when it is spelled alone, but it is Divtasvuona suohkan when using the Sami language equivalent to "Tysfjord Municipality".

The official blazon is "Argent, a lobster sable issuant from the base" (Norwegian: I sølv en oppvoksende svart hummer).

There are prehistoric rock carvings at Leiknes showing scenes of hunting, and the world's oldest known depiction of an orca whale.

[citation needed] In 1948, an investigation that had lasted for years, was dismissed in regards to "a large group of Sami from Tysfjord".

Here is a list of people who held this position:[43] Due to the limestone in Tysfjord, a cement factory was established with production starting in 1920.

[44] The modern Norcem factory still is a vital employer in Kjøpsvik, with about 130 employees; since 1999 it has been a part of the German worldwide company Heidelberger Cement.

The municipality is dominated by grey granite mountains; pine, birch, and aspen woodlands and forests; and the many fjord branches.

This 1,392-metre (4,567 ft) high natural granite obelisk, rising straight out of the fjord, is an awe-inspiring sight.

In Norwegian, it is called gudenes ambolt which means the 'anvil of the gods', partly because the summit forms a plateau.

The mountains near the border with Sweden have peaks up to 1,500 metres (4,921 ft) above sea level, and a large glacier, Gihtsejiegŋa is located in this area.

Mannfjordbotn reserve has undisturbed forests at the head of a narrow fjord branch surrounded by granite mountain walls.

For many years since 1990, a large part of the stock of Norwegian herring has stayed in the fjord in winter, one of the largest gatherings of biomass in the world.

The coastal municipality of Tysfjord is better known for its whale watching than its birdwatching but the region has still a lot to offer.

If Tysfjord experiences bad weather and the ferry connections are shut down, Norway is cut in two road-wise.
