Windeberg (pronounced [ˈvɪndəbɐɡ]) is a village and quarter of the town of Mühlhausen in Thuringia, central Germany.

Windeberg lies on the edge of the southern slope of the Dün at the transition to the Thuringian Basin, 6 kilometres (3.7 mi) north-east of the core town of Mühlhausen.

The Forstberg (395 metres (1,296 ft) above NN) lies to the south and the Flachstal (Flax Valley) nature reserve to the west.

[3] For centuries, it belonged to the sphere of influence of the Reichsstadt (imperial city) of Mühlhausen.

[5] In 1802, Windeberg, together with Mühlhausen, fell to the Kingdom of Prussia, from 1807 to 1813 to the Kingdom of Westphalia (canton Dachrieden) created by Napoleon, and after the Congress of Vienna in 1816, it was assigned to the Landkreis Mühlhausen i. Th.
