Infanta Maria Cristina of Spain, Countess Marone (Doña María Cristina Teresa Alejandra María de Guadalupe María de la Concepción Ildefonsa Victoria Eugenia de Borbón y Battenberg; 12 December 1911 – 23 December 1996) was the fourth child of Alfonso XIII of Spain and Victoria Eugenie of Battenberg and paternal aunt of King Juan Carlos I.

Infanta Maria Cristina was born at the Palacio Real in Madrid, Spain. The Spanish Royal Family left the country in 1931, in the face of Republican demonstrations, settling in Paris, before moving to Fontainebleau.

By 1933 King Alfonso and his daughters, the Infantas Beatriz and Maria Cristina, had moved to Rome. Their father warned would-be suitors of the inherent dangers of hemophilia, from which suffered two of the king's sons (Alfonso and Gonzalo).

She renounced her succession rights to the throne of the defunct Spanish crown and, on 10 June 1940, morganatically married Enrico Eugenio Marone-Cinzano (15 March 1895 Turin – 23 October 1968 Geneva) in Rome. He had been created 1st Conte Marone on 13 May 1940 by Victor Emmanuel III of Italy. He was the son of Alberto Marone and his wife, Paola Cinzano, and was the widower of Noemí Rosa de Alcorta y García-Mansilla, by whom he had issue.

The marriage produced four daughters, ten grandchildren and eleven great-grandchildren:

Infanta Maria Cristina returned to Spain and spent periods of time there, but never lived there permanently. She died in Madrid of a heart attack on 23 December 1996 during a Christmas reunion of the royal family at the Villa Giralda, the residence of her cousin and sister-in-law the Countess of Barcelona. She was given a state funeral but was buried in the Marone-Cinzano Pantheon in Turin.
