Infanta Maria Teresa of Braganza (Portuguese pronunciation:[mɐˈɾiɐtɨˈɾezɐ] or [ˈtɾezɐ]; 29 April 1793 – 17 January 1874) was the firstborn child of John VI of Portugal and Carlota Joaquina of Spain. From 1828 to 1834, she was heiress presumptive to the Portuguese throne.
Very conservative, she was an ally of her younger brother Miguel I of Portugal in his attempts to obtain the throne of Portugal (civil war 1826–1834), and of her brother-in-law and uncle Infante Don Carlos, Count of Molina in his attempts to obtain the Spanish throne. Following Miguels accession in 1828, Maria Teresa became heiress presumptive to her then childless brother, and would remain so until his deposition in 1834. In the last years of the reign of her uncle Ferdinand VII of Spain (died 1833), Teresa lived in Madrid and plotted to strengthen Don Carlos' position in succession. She participated in the First Carlist War (1833–1839), being a leading supporter of Carlism, church and reactionary interests. Her sister Francisca, Titular Queen of Spain, wife of Carlos, died in 1834.
On 15 January 1837, the Cortes of Spain legislated her excluded from the Spanish succession, rights belonging to her in descent from her mother, on grounds of her being a rebel along with Don Carlos. Her son Sebastian's rights were similarly excluded, but he was later, in 1859, restored in Spain. Also don Carlos' sons and Teresa's brother Miguel I of Portugal were excluded at the same law.
The next year she married again, in 1838, to her brother-in-law, uncle and longtime ally, Infante Carlos of Spain (1788–1855), whom she viewed as the rightful king of Spain; the widower of her sister Maria Francisca. The second marriage remained childless, but she took care of her stepsons, who were also her nephews and cousins. Following her marriage, her claim as the Miguelist heir passed to her only son by her first marriage, Infante Sebastião.
They soon left Spain because of unsuccess in the civil war, and never returned. She died in Trieste on 17 January 1874, having survived her second husband by nineteen years.
