Infante Jaime of Spain, Duke of Segovia, Duke of Anjou, RE (Jaime Leopoldo Isabelino Enrique Alejandro Alberto Alfonso Víctor Acacio Pedro Pablo María de Borbón y Battenberg) (23 June 1908 – 20 March 1975), was the second son of King Alfonso XIII of Spain and his wife Princess Victoria Eugenie of Battenberg. He was born in the Royal Palace of La Granja de San Ildefonso in Segovia Province.

Because he was deaf, as the result of a childhood operation, he renounced his rights to the Spanish throne for himself and his descendants on 21 June/23 June 1933. He was then granted the title "Duke of Segovia" by King Alfonso XIII. After his father's death in 1941, he proclaimed himself the senior legitimate male heir of the House of Capet, heir to the French throne, and head of the House of Bourbon. He then took the title of "Duke of Anjou" and became, in the opinion of French legitimists, the de jure king of France as "Henri VI", though to a minority as "Jacques II" (after 1957, he signed all documents as Jacques Henri).

In 1921, he became the 1,153rd Knight of the Order of the Golden Fleece and Knight with Collar of the Order of Charles III and Grand Cross of the Order of Isabella the Catholic both in 1925 (Collar of the Order of Isabella the Catholic in 1931).

On 4 March 1935, in Rome, Jaime married Victoire Jeanne Emmanuelle (Emanuela) Joséphine Pierre Marie de Dampierre (Rome, 8 November 1913 – Rome, 3 May 2012), daughter of Roger de Dampierre, 2nd Duque de San Lorenzo Nuovo, Vicomte de Dampierre (1892–1975) and of Donna Vittoria Ruspoli (1892–1982), daughter of Emanuele Ruspoli, 1st Principe di Poggio Suasa and his third wife English American Josephine Mary Curtis. Don Jaime and Donna Emanuela had two sons, named after Jaime's hemophiliac brothers, Alfonso and Gonzalo:
