The Tegernsee is a Zungenbecken lake in the Bavarian Alps in southern Germany. The lake is the centre of a popular recreation area 50 kilometres (31 mi) south-east of Munich. Resorts on the lake include the eponymous Tegernsee, as well as Bad Wiessee, Kreuth, Gmund, and Rottach-Egern.

The lake flows into the River Mangfall, a tributary of the River Inn and thence the River Danube.

The area around the lake is linked to Munich by rail through trains of the Bayerische Oberlandbahn, which, in the final part of their journey, travel over the tracks of the privately owned Tegernsee-Bahn. Pleasure boat services serve several points on the lake, and are operated by boats of the Bayerische Seenschifffahrt company.
