Torsö (Thor's Island) is the biggest island of the lake Vänern, area 62 km². Torsö is located in Mariestad Municipality. Torsö formerly consisted of two islands (Torsö and Fågelö), but around 1930 the water in between was pumped out, and the former seabed is now used for growing crops.
Torsö has around 550 families living year round, and around thrice that amount during summers. In 1994 a bridge, "Torsöbron", was opened between the mainland and the island. It is around 900 m long.
