Austvågøya[2] is the northeasternmost and largest of the larger islands in the Lofoten archipelago in Nordland county, Norway.

The islands surrounding Austvågøya include Gimsøya and Vestvågøya to the west, Skrova, Litlmolla, and Stormolla to the south, Hinnøya to the east, and Hadseløya to the north.

The prefix aust (which means "east") was added more recently to differentiate it from the neighboring island of Vestvågøya.

The old name of the island comes from the local farm area where the historic Vågan Church is located.

The first element of the name comes from the Old Norse word vágr which means "inlet" or "bay".
