Astafjorden (Norwegian) or Ástavierda (Northern Sami)[1] is a fjord (more accurately, a strait) in Troms county, Norway.

The 3.5-kilometre (2.2 mi) wide fjord separates the islands of Andørja and Rolla from the mainland.

[2] The fjord (and the historic Astafjord Municipality) were named after the old Ånstad farm (Old Norse: Arnastaðafjǫrðr).

[3][4] Another possible explanation for the origin of the name of the Astafjord in Troms might be that it was named after Queen Asta, mother of King "Hellige" Olav in the 11th century who allegedly brought Christianity to Norway.
