Drei Schwestern (The Three Sisters) is a mountain located on the border of Austria and Liechtenstein.

The highest peak, the Great Sister, is 2,053 metres (6,736 ft) above sea level.

The first recorded ascent was on 10 June 1870 by John Sholto Douglass from Thüringen, Vorarlberg, with a hunter named Wieser from Frastanz.

To the west, the Three Sisters fall into the Alpine Rhine Valley, in the east to the Saminatal.

The main peak can also be reached by rock climbing routes ranging from UIAA difficulty levels II to V. The north wall of the middle sister has routes with a UIAA level VI difficulty.
