The Chiemgau Alps (German: Chiemgauer Alpen) are a mountain range in the Northern Limestone Alps and belong to the Eastern Alps. They are crossed by the Austria–Germany border: their major part is situated in Bavaria, Germany, and only a small section is within the states of Salzburg and Tirol in Austria. They reach their highest elevation (1,961 m (6,434 ft)) in the Sonntagshorn, a peak straddling the German-Austrian border.

The Chiemgau Alps stretch from the Inn River in the West to the Salzach River in the East and cover a distance of 60 km (37 mi) in strike direction; their maximum width in North-South direction amounts to about 25–30 km (16–19 mi). They are surrounded by the following mountain ranges:

• Bavarian Prealps in the West
• Kaisergebirge in the Southwest
• Leoganger Steinberge in the South
• Loferer Steinberge in the Southeast
• Berchtesgaden Alps in the Southeast and East

Their northern edge often drops off quite drastically to the foothills.
