Bärenmühle, Multifamily residential building in Wieden district, Vienna, Austria.

Bärenmühle is a wedge-shaped apartment building between Rechte Wienzeile and Operngasse, at the edge of Karlsplatz in Vienna's Wieden district. Heinrich Schmid and Hermann Aichinger designed it in 1937/38. A ground-floor passage, the Bärenmühldurchgang, runs through the building as a pedestrian link between Operngasse and Rechte Wienzeile. A relief plaque by Oskar Thiede on the facade depicts the bear attack of the legend.

A mill operated on the neighbouring plot, roughly Rechte Wienzeile 3, from 1705 to 1794, then moved to the adjacent site and ran until 1856, when the Mühlbach was filled in. The poet Ignaz Franz Castelli lived in the mill and died in 1862. The Freihaus was demolished from 1930, and the wedge-shaped building by Heinrich Schmid and Hermann Aichinger followed in 1937/38.

The building takes its name from a neighboring tavern called 'Zum schwarzen Bären' rather than from local folklore about a bear encounter. The name has stayed with the place even though the original tavern no longer exists.

Access to the building is from Rechte Wienzeile, a main street with multiple transportation connections nearby. Visitors should note this is a private residential building and only the exterior is viewable.

A relief plaque by sculptor Oskar Thiede on the house shows the legendary bear attack, placing the event in 1660. The mill itself stood on the neighbouring plot, roughly at Rechte Wienzeile 3, and was moved there in 1794 before the millrace was filled in 1856.
