Prince Pedro Gastão of Orléans-Braganza (19 February 1913 – 27 December 2007) was the Head of the Petrópolis branch of the House of Orléans-Braganza and a claimant to the defunct Brazilian throne in opposition to the Vassouras branch claim led by his cousins Princes Pedro Henrique and Luiz.Pedro Gastão was born during the exile of the Brazilian Imperial Family, being the second child and first son of Pedro de Alcântara, Prince of Grão-Pará, sometime heir to the throne of the Empire of Brazil, and Countess Elisabeth Dobrzensky of Dobrzenicz. Never having accepted his father's 1908 renunciation as valid, he actively claimed the Brazilian throne from his father's death in 1940 until his own in 2007.
