The Sanna is a river of Tyrol, Austria, a left tributary of the Inn.

The Sanna is formed near Tobadill by the confluence of the rivers Rosanna [ceb; cs; da; de; fr; nl; pl; sh; sv] (42 km (26 mi), from Arlberg and the valley Stanzertal [ceb; de; nl; sv]) and Trisanna [ceb; da; de; fr; nl; pl; sv] (31 km (19 mi), from Silvretta and Paznaun). It flows into the Inn at the small town of Landeck. It is 7.1 kilometres (4.4 mi) long. Its basin area is 727 km² (281 sq mi).^[1] The villages Pians and Grins are situated at its waterfront.
