Maria Anna of Savoy (Maria Anna Carlota Gabriela; 17 December 1757 – 11 October 1824) was a Princess of Savoy by birth and Duchess of Chablais by her marriage to her uncle.

Born at the Royal Palace of Turin, she was the sixth child of Prince Victor Amadeus, Duke of Savoy and, since 1773, King of Sardinia, by his wife, Maria Antonia Ferdinanda of Spain, as daughter of Philip V.

Maria Anna was the fourth but third surviving daughter of her parents. Her two older sisters were the future "grand daughters in law" of Louis XV of France, Princess Maria Giuseppina, who married the future Louis XVIII of France in 1771 and Princess Maria Teresa, who married the future Charles X of France in 1773. Their younger surviving sister, Maria Carolina, married Anthony of Saxony.

Three of her brothers were the last three Kings of Sardinia from the senior line of the House of Savoy: the future Charles Emmanuel IV, Victor Emmanuel I and Charles Felix. After the death of the last one in 1831 without issue, the throne passed to Charles Albert, Prince of Carignano and next legitimate male heir.

After the weddings of her older sisters to French Princes, was arranged the marriage between Maria Anna and her paternal uncle Prince Benedetto, Duke of Chablais, younger half-brother of Victor Amadeus III (as the son of Charles Emmanuel III of Sardinia and his last wife, Elisabeth Therese of Lorraine). The wedding took place on 19 March 1775 at the Chapel of the Holy Shroud in Turin. They had no children but had a happy union: although they were close, Maria Anna always saw him as her uncle. Their official residence were the Palazzo Chiablese and the Ducal Castle of Agliè. She had good relationships with her sisters-in-law Marie Clotilde of France, Princess of Piedmont and Maria Theresa of Austria-Este, Duchess of Aosta.
