Västmanlands-Dala nation, mostly referred to only as V-Dala, is one of the 13 student nations at Uppsala University in Sweden. The nation, intended for students from the provinces of Dalarna and Västmanland – these provinces making up most of the diocese of Västerås – was founded in 1639. The first inspektor of the nation was Olof Rudbeck the Elder, appointed in 1663. The current is Johan Tysk, professor, Department of Mathematics, Uppsala University.
The house of Västmanlands-Dala nation is one of three buildings in Sweden designed by the world-famous Finnish architect Alvar Aalto. The house was built in 1965, and was paid for by fund-raising in Dalarna and Västmanland.
