The Ötztaler Ache is a river in the district of Imst, Tyrol, Austria, a right tributary of the Inn.

The Ötztaler Ache flows through the Ötztal valley, a southern branch the Inntal. Including its source rivers Venter Ache and Rofenache, it is 66.5 kilometres (41.3 mi) long. The Rofenache is the runoff of the Hintereisferner, a glacier at the foot of the Weißkugel, Ötztal Alps. At Vent, near Sölden, it takes up the Niedertalbach and its name changes to Venter Ache. At the confluence with the Gurgler Ache in Zwieselstein, Sölden, the Ötztaler Ache proper is formed. It flows through Sölden, Längenfeld, Umhausen and Oetz before joining the Inn 8 kilometres (5.0 mi) east of Imst. The river is one of its bigger tributaries.
