Teresa Magbanua y Ferraris, better known as Teresa Magbanua and dubbed as the "Visayan Joan of Arc", was a Filipino schoolteacher and military leader. Born in Pototan, Iloilo, Philippines, she retired from education and became a housewife shortly after her marriage to Alejandro Balderas, a wealthy landowner from Sara, Iloilo. When the 1896 Philippine Revolution against Spain broke out, she became one of only a few women to join the Panay-based Visayan arm of the Katipunan, the initially secret revolutionary society headed by Andrés Bonifacio.
