The Merkur or Großer Staufenberg is a mountain, 668.3 m above sea level (NHN),[1] in the Northern Black Forest, Baden-Württemberg, Germany.

Today, there is a cast of the original votive stone on the summit plateau; its prototype is in the Baden-Baden Municipal Museum collection.

[2] The original name of the free-standing conical mountain was the Großer Staufenberg, a reference to the shape of a turned drinking mug known as a Stauf.

A more recent reinforced concrete annex supports an antenna mast made of steel, reaching a total height of 63 metres (207 ft).

The mountain has an all-round view, not just over the bowl of Baden-Baden, the highest peaks of the Northern Black Forest and the Murg valley with the towns of Gaggenau and Gernsbach, but also of the Upper Rhine Plain, the Vosges, the Haardt and the Odenwald.
