Andørja (Norwegian) or Áttir (Northern Sami)[1] is an island in Ibestad Municipality in Troms county, Norway.

The Vågsfjorden lies to the north and west of the island and the Astafjorden flows along the southeastern coast.

The highest point on the 135-square-kilometre (52 sq mi) island is the 1,276-metre (4,186 ft) tall mountain Langlitinden.

The 8-kilometre (5.0 mi) long Straumbotn fjord cuts into the middle of the island from the north side.

The last element is yrja which means "gravel" or "rocks", possibly referring to the waves from the sea hitting against the rocky shores.
