The Haas House is a building in Vienna at the Stock-im-Eisen-Platz.
Designed by the Austrian architect Hans Hollein, it is a building in the postmodernist style and was completed in 1990. The use of the Haas-Haus is divided between retail and a restaurant. The building is considered controversial owing to its contrast with the adjacent Stephansdom cathedral.
