Leonor, Princess of Asturias (Leonor de Todos los Santos de Borbón y Ortiz; born 31 October 2005) is the heir presumptive to the Spanish throne. She is the elder daughter of King Felipe VI and Queen Letizia.

Leonor was born during the reign of her paternal grandfather, King Juan Carlos I. She was educated at Santa María de los Rosales School, like her father; after finishing her secondary studies, she studied for an International Baccalaureate at the UWC Atlantic College in the Vale of Glamorgan in Wales, United Kingdom. In 2014, following her father's accession to the throne after the abdication of her grandfather, Leonor was granted all the traditional titles of the heir to the Spanish crown. These are Princess of Asturias, Princess of Girona, Princess of Viana, Duchess of Montblanc, Countess of Cervera, and Lady of Balaguer. Leonor was formally proclaimed heiress before the Cortes on 31 October 2023, her 18th birthday.

Before pursuing higher education, Leonor completed three years of military training, graduating as an officer in all three branches of the Spanish Armed Forces. Since September 2026, she has been studying Political Science at the Charles III University of Madrid.
