Maria Vittoria dal Pozzo, French-Italian wife of Amadeo I of Spain (died 1876)

Maria Vittoria Carlotta Enrichetta Giovanna dal Pozzo, 6th Princess of Cisterna d'Asti and of Belriguardo, was an Italian noblewoman who was Queen of Spain from 16 November 1870 until 11 February 1873 as the wife of King Amadeo I. Maria Vittoria inherited her princely title after the death of her father. In 1867, she married Amadeo, then Duke of Aosta, second son of King Victor Emmanuel II of Italy. In 1870, her husband became the king of Spain, making her queen consort. King Amadeo abdicated after a reign of less than three years, and he and Maria Vittoria returned to Italy. She died in Sanremo, Italy, in 1876.

Amadeo I, also known as Amadeus, was an Italian prince who reigned as King of Spain from 1870 to 1873. The only king of Spain to come from the House of Savoy, he was the second son of Victor Emmanuel II of Italy and was known for most of his life as the Duke of Aosta, the usual title for a second son in the Savoyard dynasty.
