The Château de Châtillon-Coligny is a castle, later replaced with a smaller château, in the commune of Châtillon-Coligny in the Loiret département of France.

The present structure is heavily modified. Its origins were a medieval fortress whose keep was constructed around 1180. The castle was rebuilt during the Renaissance and demolished from 1798. A new, more modest château was constructed in 1854. Of the original, the keep and a Renaissance well, attributed to Jean Goujon, are the only remains.

The castle is built on a plateau dominating the Loing valley.

The gallery terrace was decorated by Francesco Primaticcio (Le Primatice) and Jean Goujon and the pavilion contained a staircase. Gaspard II also built the sculptured well, attributed to Goujon, and the orangery, one of the first in the country and described as "the most beautiful of the orangeries constructed in France in the 16th century".
