Beatrice of Castile or Beatriz (8 March 1293 – 25 October 1359), was an infanta of Castile, daughter of Sancho IV and María de Molina. She was queen consort of Portugal from 1325, when her husband, Infante Afonso, succeeded his father, King Denis, as Afonso IV, until his death on 28 May 1357.

Daughter of Sancho IV and of María de Molina, Infanta Beatrice was born in Toro. She had six siblings, including King Ferdinand IV of Castile and Queen Isabella, wife of King James II of Aragon, and later duchess as the wife of John III, Duke of Brittany.

On 13 September 1297, when Beatrice was only four years old, the bilateral agreement, known as the Treaty of Alcañices, was signed between Castile and Portugal, putting an end to the hostilities between both kingdoms and establishing the definitive borders. The treaty was signed by Queen María de Molina, as the regent of Castile on behalf of her son, Ferdinand IV, who was still a minor, and King Denis of Portugal. To reinforce the peace, the agreement included clauses arranging the marriages of King Ferdinand and Constance of Portugal and that of her brother, Afonso, with Beatrice; that is, the marriage of two siblings, infantes of Portugal, with two other siblings, infantes of Castile.

Beatrice abandoned Castile in the same year and moved to the neighboring kingdom where she was raised in the court of King Denis together with her future spouse, Infante Afonso, who at that time was about six years old. Her future father-in-law "had inherited from his grandfather, Alfonso X of Castile, a love of letters, literature, Portuguese poetry, and the art of the troubadours" and Beatrice grew up in this refined environment. Two of the Portuguese king's illegitimate sons, both important figures in the kingdom's cultural panorama, were also at the court: Pedro Afonso, Count of Barcelos, a poet and troubadour and the author of Crónica Geral de Espanha and the Livro de Linhagens; and, Afonso Sanches, the favorite son of King Denis and a celebrated troubadour.
