The Kleiner Kranichsee (literally "Little Crane Lake", Czech: Malé jeřábí jezero) is one of the most important raised bogs in the Ore Mountains of Central Europe.
The raised bog is located at an elevation of 930 metres above sea level (NN) in a clearing in the highland forest southwest of the town of Johanngeorgenstadt.
The border between Germany and the Czech Republic runs through the bog and continues over the mountain of Buchschachtelberg.
The name of the raised bog is linked to the Czech word granica "meaning border".
By the turn of the century, the Ore Mountain Club branch at Johanngeorgenstadt laid a corduroy road into the bog and set up a viewing stand, which has since been replaced several times.
