Gy (French pronunciation: [ʒi]) is a commune in the Haute-Saône department in the region of Bourgogne-Franche-Comté in eastern France.

In 1389, a dispute arose over the rights to mint coins between the Duke of Burgundy, and the Archbishop of Besançon Guillaume de Vergy.

In response, the Duke of Burgundy gave siege to the fortresses of Noroy and the castle of Gy.

However, the Archbishop escaped via an underground passage and found refuge in Avignon where he excommunicated the count of Burgundy.

[3] By 1801, the population of the town had reached 2,695, and peaked about a decade later.
