Viðvíkursveit is a district in Skagafjörður, Iceland east of the Héraðsvötn, on the border of Akrahreppur along the Kyrfisá river[1] to Kolka and on the east side towards the mouth of Hjaltadalur valley.

Viðvíkurfjall waterfall overlooks the eastern portion of the area, and to the west is the Héraðsvötn, followed by Lónssandur beach on the outside of Austurós estuary.

The region was settled by the explorer Öndóttur who lived in Viðvík, in the easternmost part of the district.

The woods, mentioned in the Landnámabók, are now a hilly area too windy to support tree growth.

Recently, enthusiasts have formed a group to revive Brimnes woods using only seeds from what little remains of the forest that was in Skagafjörður and has grown there since the Age of Settlement, especially in Geirmundarhólur forest in Hrolleifsdalur valley.
