Formarinsee is a lake in the Austrian Alps. It lies in the Bundesland of Vorarlberg and lends its name from the mountain pasture Formarinalpe.
As part of the ORF TV program "9 places, 9 treasures", the Formarinsee with the Rote Wand (2 km north of the lake) was voted Austria's most beautiful place on 24 October 2015.
