Maria Cristina of Naples and Sicily (Maria Cristina Amelia Teresa; 17 January 1779 – 11 March 1849) was a Princess of Naples and Sicily and later Queen of Sardinia as wife of Charles Felix of Sardinia. 
Princess of Naples and Sicily.
She was a daughter of King Ferdinand I of the Two Sicilies and his wife Maria Carolina of Austria, a daughter of Empress Maria Theresa of Austria. She was her mother's favourite child.

She was married on 6 April 1807 in Palermo with Prince Charles Felix of Savoy, who became King unexpectedly, when his two elder brothers abdicated, Charles Emmanuel IV of Sardinia in 1802 and Victor Emmanuel I of Sardinia in 1821. Till her husband became king, she was styled as the "Duchess of Genevois".
Queen of Sardinia.
The royal couple were interested in the arts and artists, and turned the Royal House in Agliè and the Villa Rufinella in Frascati into comfortable residences. 
During her husband's reign, they resided at the Palazzo Chiablese, where her husband died in 1831. 
In 1825, the Queen engaged the archaeologist Marquess Luigi Biondi (1776–1839), whose excavation work uncovered Tusculum. In 1839 and 1840, the architect and archaeologist Luigi Canina (1795–1856) was engaged by the royal family and excavated the Theatre area of Tusculum. The ancient works of art excavated were sent to the Duke of Savoy's Castle of Agliè in Piedmont.
Charles Felix died in 1831 after a reign of ten years. Maria Cristina lived the rest of her life in Turin, Naples, Agliè and Frascati, and died in Savona, Liguria.
