Châteaudun (in French pronounced as /ʃɑtodœ̃/) is a commune in the Eure-et-Loir department in northern France. It is a sub-prefecture of the department. It was the site of the Battle of Châteaudun during the Franco-Prussian War.
Châteaudun is located about 45 km northwest of Orléans, and about 50 km south-southwest of Chartres. It lies on the river Loir, a tributary of the Sarthe.
Châteaudun (Latin Latin: Castrodunum), which dates from the Gallo-Roman period, was in the middle ages the capital of the County of Dunois.
The streets, which radiate from a central square, have a uniformity due to the reconstruction of the town after fires in 1723 and 1870.
The area is rich agricultural land, but a major local employer is the Châteaudun Air Base just to the east of the town, and much larger than the town itself.
The town has a château, founded in the 10th century, known for being the first on the road to Loire Valley from Paris.Châteaundun also has a museum, the French: "Musée des beaux arts et d'histoire naturelle"|italic=no.
