Dona Maria Francisca (8 September 1914 – 15 January 1968) was the daughter of Pedro de Alcântara, Prince of Grão-Pará, head of the Petrópolis line of the House of Orléans-Braganza.

Maria Francisca Amélia Luísa Vitória Teresa Isabel Miguela Gabriela Rafaela Gonzaga was born at Château d'Eu in Eu, France, the daughter of Pedro de Alcântara, Prince of Grão-Pará (1875–1940), the eldest son of Isabel, Princess Imperial of Brazil and grandson of Emperor Pedro II, and Countess Elisabeth Dobrzensky of Dobrzenicz (1875–1951), a Bohemian noblewoman.

Maria Francisca died in Lisbon and was buried at the Chagas de Cristo (Jesus's Five Sacred Wounds) Convent, in Vila Viçosa, the pantheon of the duchesses of Braganza.

The religious ceremony took place in the Cathedral of Petrópolis and was presided by Cardinal Sebastião Leme da Silveira Cintra, Metropolitan Archbishop of Rio de Janeiro.

The Rite of Marriage was followed by a Nuptial Mass, and the newlyweds received an Apostolic Blessing from Pope Pius XII, according to a telegram that was read on the occasion.

Since the civil ceremony did not take place before the Brazilian authorities but in the Portuguese Embassy, a question then arose regarding the manner of recognizing the marriage in the Law of Brazil.
