Nançay (French pronunciation: [nɑ̃sɛ]) is a commune in the Cher department in central France.

The village is located south of the Sologne and northeast of Vierzon.

The territory belonged successively to the County of Sancerre and the area of La Chatre.

Joan of Arc stayed there, leaving her name to the spring maiden.

Its castle dates from the fifteenth century, and was rebuilt during the Renaissance.
