Zahna is a town and a former municipality in Wittenberg district in Saxony-Anhalt, Germany not far from Federal Highway (Bundesstraße) B 2 and about 11 km east of Lutherstadt Wittenberg.

This has been established by archaeological findings from the 6th century BC up until the migration of the Semnoni who settled in the region.

The historic town core shows the form and structure that goes back to Flemish settlement in the High Middle Ages in the twelfth century.

The whole highland north of Wittenberg was so strongly shaped by the Flemings' ways of doing things that the whole area came to be named after them; to this day, it is still called the Fläming and the town belongs to the Fläming Nature Park, which was opened in 2005.

After World War II, Zahna was incorporated into the State of Saxony-Anhalt from 1945 to 1952 and the Bezirk Halle of East Germany from 1952 to 1990.
