Auersberg, Mountain summit in Eibenstock, Germany.

Auersberg is a 1,018.2 m high mountain in the Ore Mountains, on the Wildenthal district of Eibenstock near the Czech border. Its main rock is medium-grained granite containing tourmaline, with silver, tin and iron compounds mined from the 16th century. The summit and part of the eastern slope are covered by an 80 m thick andalusite-mica layer; quartz and slate occur in veins at the top.

In earlier centuries, the area around the mountain was an important mining region, especially during the peak of ore extraction in the 16th century. Mining then heavily shaped the life and economy of the surrounding communities.

The Auersberg area was a favourite hunting ground of Saxon electors, who pursued red deer and capercaillie here. Since 13 July 2011 a bilingual German-Czech educational trail, the "Bergwaldgarten Auersberg", has run across the mountain. The summit inn, opened in 1907 on the initiative of the Erzgebirgsverein, still serves as the mountain's meeting point.

The mountain is reachable via established hiking trails, with a parking area at the base serving as a starting point. The paths are easy to access, though visitors should be prepared for uneven terrain and changing weather conditions at higher elevations.

The Auersberg summit carries a radar installation built from August 1983 to November 1985 for the East German Ministry for State Security; locals called it the "Stasi Mosque" because of its dome. After reunification, failed plans for a museum or hostel gave way to Deutsche Flugsicherung, which has run the SREM radar here since the 1990s, one of six sites with a range of about 145 nautical miles.
