[1] Åstol is an island and a locality in Tjörn Municipality in Rönnäng Parish situated in the Province of Bohuslän.

The village had amenities like a shore cash desk that provided everything needed for fishing, a number of grocery stores, and a bakery.

From 1918 onwards, Åstol and Tjörnekalv became part of the newly formed Rönnäng rural municipality.

The island gained further recognition when the Swedish comedy troupes Galenskaparna and After Shave filmed their satirical story "Åke från Åstol" there in the summer of 1998.
