Aubøsund or Audbøsund is a small strait between the islands of Aubø and Bjergøy in the Sjernarøyane archipelago in the northeastern part of the large Stavanger Municipality in Rogaland county, Norway.
The strait was the site of an old trading place and transportation hub, and today there remains a wharf, store, and post office.
The name probably comes from a combination of the Old Norse male name Audi and the word bø which means "farm".
[1] A burial mound at Steinneset suggests that the place has been inhabited since the Iron Age.
Since the earliest writings in the 1500s, Aubøsund has been a croft, belonging to the farm at Aubø.
