Lichtsee is a lake in Tyrol, Austria. It lies northern above the village Obernberg am Brenner on 2.100 metres above sea level. He can only be reached on foot from the village. With an area size of 3.93 ha it is one of the bigger lakes at such a high altitude.

Due to his protected location the Lake possesses an excellent water quality (A Grade). In hot summers the Lake invites for jumping into the clear water which hardly warms up to more than 14°C. On the southern shore grow lots of blueberries and cranberries. Several kinds of trouts live also in the water. The Lake gets water only through rain and melting of snow.
