Duarte Pio, Duke of Braganza

Dom Duarte Pio, Duke of Braganza (Portuguese: Duarte Pio de Bragança, born 15 May 1945) is the current Duke of Braganza and a claimant to the dormant Portuguese throne, as the head of the House of Braganza. The Miguelist Braganzas, to whom Duarte Pio belongs as great-grandson of King Miguel I, is a cadet branch of the House of Braganza. With the extinction of male-line dynasts descended from Queen Maria II in 1932, King Miguel's descendants became the only male-line Braganzas remaining and the closest male-line heirs to the defunct Portuguese throne.

Duarte Pio is a figure within the European network of royal houses, often being invited to various foreign royal events. Despite his support for a monarchical government and widespread recognition as pretender to the throne, there are no major movements or parties that support restoration of the monarchy.

In 1995, the Duke married Isabel Inês de Castro Curvelo de Herédia, a Portuguese businesswoman and descendant of Portuguese nobility. Their marriage was the first marriage of a Portuguese royal to happen in Portuguese territory since the marriage of King Carlos I and Princess Amélie of Orléans, in 1886. The Duke and Duchess have three children, thus continuing the line of the Braganzas, as neither of the Duke's brothers has married or had children.

The Duke of Braganza holds Portuguese citizenship, by birth, and East Timorese citizenship due to high service to the country.
