Marie Victoire Sophie de Noailles, Countess of Toulouse (6 May 1688 in Versailles – 30 September 1766 in Paris), was a French noble and courtier.

After two years of marriage, Marie Victoire gave birth to the couple's only child, a son, the sole heir of his father: The comte and comtesse de Toulouse had official rooms at Versailles.

Their apartments, which later were given to the daughters of the new king, Louis XV, were situated on the ground floor of the palace and were the former suite of rooms which had belonged to the comte's mother, Madame de Montespan.

The chosen bride was an Italian princess, Marie Thérèse Félicité d'Este, who was also a descendant of Madame de Montespan.

According to Nancy Mitford's book on Madame de Pompadour, she was the only woman who was allowed to see the young king without an official appointment.

[2] On 30 September 1766, Marie Victoire died at the Hôtel de Toulouse, the Parisian townhouse bought by her husband in 1713.
