François de Coligny (1557–1591) comte de Coligny and seigneur de Châtillon-sur-Loing was a French Protestant general of the Wars of Religion. He was the son of Gaspard II de Coligny (1519–1572), Admiral of France (Amiral de Coligny).
He first saw action at the defence of Montpellier during the Sixth War of Religion (1576–1577). First he razed the citadel, guarded by royal soldiers. Then, when the situation became difficult, he made a sortie across the Cévennes to Bergerac to recruit reinforcements and fought his way back into the town.
At the start of the war of the Catholic League, when king Henry III had practically no other support, he beat the Duke of Mayenne near Chartres in 1589.
He distinguished himself at the battle of Arques (September 1589), where his arrival at the head of 500 arquebusiers allowed the victory of Henry IV to be expanded upon.
On 18 May 1581, he married Marguerite d'Ailly (?-1604), daughter of Charles d'Ailly seigneur de Seigneville. They had 4 children:
