Château-Chalon (French pronunciation: [ʃato ʃalɔ̃]) is a commune in the Jura department, Bourgogne-Franche-Comté, eastern France.

[3] The commune is perched on a cliff in the first fold of the Jura mountains.

It is reached from the west by a road with numerous hairpin curves.

Its location has earned its nomination as one of the Most Beautiful Villages of France.

[4] Although the west side of the village is a sheer cliff, the east side slopes gently away in vineyards known for their wine, including their white wine, Château-Chalon AOC.
