The Château de Fougères-sur-Bièvre is a castle in the commune of Fougères-sur-Bièvre in the Loir-et-Cher département of France.
Originally an 11th century structure, it was entirely rebuilt at the end of the 15th century, only the large square keep being preserved. The first works kept the military aspect (ditches, cannon-holes, wall walk, etc) but, thereafter, more Renaissance refinements were added such as a gallery, mullioned windows and steep-sloped roofs. During the 19th century, a spinning mill was installed in the chapel. The castle was purchased and restored by the state in the 1930s.
It has been listed since 1912 as a protected monument historique by the French Ministry of Culture.
