Dona Isabel, Duchess of Braganza (née Isabel Inês Castro Curvello de Herédia; born 22 November 1966), is a Portuguese businesswoman who married Duarte Pio, Duke of Braganza, the current pretender to the defunct Portuguese throne.

Isabel Inês Castro Curvello de Herédia was born on 22 November 1966, in Lisbon, to Dom Jorge de Heredia (b. 1934), an architect, and Raquel Leonor Pinheiro de Castro Curvello (b. 1935), his wife.

Since birth, she was entitled to the honorific styling of Dona (Lady), being a descendant in the male lineage of Francisco Correia de Herédia, Viscount of Ribeira Brava (a Vitalício title, meaning Life peerage) and his wife Dona Joana Gil de Borja de Macedo e Meneses (1851-1925). Although Francisco was member of the Portuguese nobility, he was a famed republican, who was involved in the failed republican uprising of 28 January 1908.
