The Srirangam Srimad Andavan Ashramam is a Hindu institution of the Sri Vaishnava tradition dedicated to the propagation of Ramanuja's and Vedanta Desika's philosophy of Vishishtadvaita. The head of the institution is known as the "Andavan" or "Andavan Swamigal", a title that is believed to be given by the deity Ranganatha himself to the first seer.
It is often listed with other institutions of this tradition, such as the Parakala Matha, Ahobila Matha and the Poundarikapuram Andavan Ashramam.
The main activities of the institution include conducting the sacraments of samashrayana and bharanyasa, kalakshepams (higher spiritual lessons), and Vedic and Western education through schools and secular colleges, managing and funding various temples and Divya Desams, and spreading the teachings of Ramanuja through its various centres.
