Alagiya Manavalan, best known by his epithet Manavala Mamunigal lit. 'The great saint, Manavalan' (1370–1450), was a Hindu theologian. He was a major proponent of the Sri Vaishnavism tradition in the 15th century in Tamilakam, disseminating it with the help of his eight disciples. The disciples of Manavalan established places of learning to teach the Vishishtadvaita philosophy in Tamilakam. Yathindra Pravana Prabhavam by Pillai Lokam Jeeyar is the earliest work on which scholars and historians rely for information for the biography of Manavala Mamunigal.
