Musa balbisiana is a species of wild banana native to South Asia. It is one of the ancestors of modern cultivated bananas along with Musa acuminata. It grows lush leaves in clumps and grows with a more upright habit than most cultivated bananas. Flowers grow in inflorescences coloured red to maroon. The fruit are between blue and green. They are considered inedible because of the seeds they contain. Seeded Musa balbisiana are called "butuhan" ('with seeds') in the Philippines
