Prince Ataúlfo of Orléans (20 October 1913 – 8 October 1974), was a Spanish prince, the youngest son of Infante Alfonso, Duke of Galliera and Princess Beatrice of Edinburgh.

[1] He was born in Madrid, as the third and last son of Infante Alfonso, Duke of Galliera (elder son of Infante Antonio, Duke of Galliera, and of Infanta Eulalia of Spain) and Princess Beatrice of Saxe-Coburg and Gotha (youngest daughter of Alfred, Duke of Saxe-Coburg and Gotha, and of Grand Duchess Maria Alexandrovna of Russia).

His godparents were Infante Carlos of the Two-Sicilies, and Isabella de Borbón.

He was idolised by Priscilla Scott-Ellis who was not deterred by his mother who hinted that he was not interested.

[4] Only he and two of his cousins, Luis Alfonso and José Eugenio of Bavaria (Prince Fernando of Bavaria's sons) represented the Spanish royal family in Francoist official acts, due to the pro-democratic views held by most of the royal family.
