The Mittlerer Sonnblick is a 3,000 metre high sub-peak of the Großer Sonnblick (3,030 m) to which it is linked by a knife-edge ridge. It is a border peak between the two Austrian federal states of Carinthia and Salzburg. It lies within the Ankogel Group of mountains, a sub-group of the High Tauern.

The mountain has a prominence of 100 metres and an isolation of 660 metres.

The peak has achieved certain renown, no doubt because it is the easternmost three-thousander in the Alps. It is certainly not wrong to say that the Großer Sonnblick is the easternmost mountain in the Alps that exceeds the 3,000-metre mark, but it is not the easternmost point in the Alps that reaches that height.
