Antoinette de Maignelais (French pronunciation: [ɑ̃twanɛt də mɛɲlɛ]; 1434–1474) was the cousin of Agnès Sorel, favorite mistress of Charles VII of France until her sudden death in 1450.
Married to André de Villequier, one of the king's mignons, she enjoyed a short but fruitful marriage, bearing two sons, until his death in 1454.
Through her father she was a first cousin of Agnès Sorel, who was Charles VII's mistress from roughly 1444 until her sudden death of mercury poisoning in 1450.
In her sixteenth year, shortly after Agnès died, Antoinette joined the tight band surrounding Charles VII; some chroniclers presumed that she was his new mistress.
[2] On this occasion the king presented Antoinette with the isles of Oleron, Marennes, and Arvert as a marriage portion, with a pension of 6,000 livres a year for life.
