Wannweil is a town in the district of Reutlingen in Baden-Württemberg in Germany. It is located 5 kilometers northwest of Reutlingen between the cities Reutlingen and Tübingen.

It was home of 1990 soccer world champion Guido Buchwald and of Germany's former president Horst Köhler during his study period in Tübingen.

Wannweil was first mentioned in a 1257 Document as Wyle bi Betzingen, the name Wannwyle first appearing in 1465. In 1333, Albrecht of Blankenstein sold Wyle to the Spital of Reutlingen. Since then, it shares its history with the city. With the Treaty of Paris, Wannweil and Reutlingen were given to the Kingdom of Württemberg.
