Diane de Poitiers (3 September 1499 – 25 April 1566) was a French noblewoman and a prominent courtier at the courts of kings Francis I and Henry II.
She wielded much influence and power at the French court as King Henry's chief mistress.
She continued in this role until Henry was mortally wounded in a tournament accident.
During that tournament his lance wore her favour (ribbon), rather than his wife's.
Poitiers is subject of paintings by François Clouet as well other anonymous painters.
Diane was also immortalised in a statue by Jean Goujon.
