The House of Coligny was the name of an old and important French noble family, originating from the Bresse region of France.

The head of the family held the title Duke of Châtillon, created in 1643.

This family produced two Marshals of France, a Lieutenant-General of the French infantry, two Admirals, a Cardinal, Bishop of Beauvais, and an Archbishop of Lyon.

The possessions of the Coligny family probably arose in the 10th century from the break-up of the pagus (rural subdivision of a tribal territory) of Bresse, which was commonly called the Manche des Coligny.

A town in Revermont, Coligny was located on the borders of two principalities of the Holy Roman Empire: the County of Burgundy in the region of Franche-Comté (for the northern part, or Coligny-le-Vieux: in the department of Jura; later the Marquisate of Coligny);[3] and the Savoyard state (for the southern part, or Coligny-le-Neuf: in the department of Ain; later the County, and then Duchy, of Coligny).
