Infante Alfonso of Spain, Prince of the Two Sicilies, Duke of Calabria (30 November 1901 – 3 February 1964) was one of two claimants to the title of the head of the House of Bourbon-Two Sicilies from 1960 until his death in 1964. He was the son of Prince Carlos of Bourbon-Two Sicilies and María de las Mercedes, Princess of Asturias. He was born and died in Madrid, Spain.
Alfonso's mother was María de las Mercedes, Princess of Asturias, but she died in childbirth in 1904. Alfonso XIII, King of Spain, was unmarried at the time so as the Princess of the Asturias's eldest son, the young infante became heir presumptive to the Spanish crown, though, unlike his mother, he never held the title of Prince of Asturias. He was heir presumptive until the birth of his cousin, Alfonso, to Alfonso XIII and Queen Victoria Eugenie in 1907.
