(born Nov. 25, 1638, Vila Viçosa, Port.—died Dec. 31, 1705, Lisbon) Portuguese wife of Charles II of England. She was married to Charles in 1662 as part of an alliance between England and Portugal, bringing England trading privileges and the port cities of Tangier and Bombay (now Mumbai). She produced no heir. Though not a faithful husband, Charles defended her against accusations of scheming to poison him. She helped convert him to Catholicism shortly before his death. In 1692 she returned to Portugal, and in 1704 she governed the country as regent for her ailing brother, Pedro II.
