Polignac (; ) is a commune in the Haute-Loire department in south-central France. It is a member of Les Plus Beaux Villages de France (The Most Beautiful Villages of France) Association.
The town is dominated by the Forteresse de Polignac with its square donjon tower, 32 m tall. The Chateau de Lavoute Polignac is a few miles away, close to the village of Lavoute.
The poetical illustration "The Church at Polignac" by Letitia Elizabeth Landon to a painting by James Duffield Harding was written during the imprisonment of Prince Polignac and his colleagues, after the French Revolution of 1830 (in Fisher's Drawing Room Scrap Book, 1837).
