Tettinang or Tettinac was first mentioned in 882 in a document of the Abbey of St. Gall. In the beginning of the 10th century the castle of the Counts of Montfort was built near the town. The town privileges were granted in 1294 by King Adolf of Nassau. The reign of the Counts of Montfort ended 1780 when they sold the county to Austria, along with Tettnang Castle to pay debts. The county became part of Further Austria under the house of Habsburg. In the Peace of Pressburg of 1805 it became Bavarian property which gave it to Württemberg five years later. With the merge of Baden, Hohenzollern and Württemberg in 1952 it became part of the new formed state Baden-Württemberg. Until 1973 it was capital of the district Tettnang which was merged with parts of district of Überlingen to form the Bodenseekreis
The second release of the Linux operating system Fedora was named "Tettnang" because of the hops grown in Tettnang being used for making beer. The release was preceded by the beer-related name "Yarrow" (an early substitute for hops) and followed by "Heidelberg" (a German city and the name of a distributor of beer).
