The Acherkogel is a mountain in the Austrian Alps with a 3,008 m above sea level (AA) high summit.

It dominates the village of Oetz in the lower valley of the River Ötz, where high rock faces rise to the northwest and southwest.

Another sharp ridge heads southeast to the 2,954 m high Wechnerkogel.

In the main, the Acherkogel has the character of a rocky peak, only to the north and east are there small snowfields.

It was first climbed on 24 August 1881 by Ludwig Purtscheller from the southeast and south ridge over a route that has not been used since.
