Srirangam Srimad Andavan Ashramam is an institution that is over three hundred years old, and belongs to the Sri Vaishnava tradition. It follows the teachings of vishishtadvaita, as propounded by Bhagavad Ramanuja and Srimad Vedanta Desika.

The main spiritual headquarter of the Andavan Ashramam is in Srirangam, where most acharyas of this lineage have spent their saintly lives.

The institution has over 35 centres spread across India and the US. The institution also runs the Andavan Arts and Science College, several veda-patasalas, and goshalas.

The main symbol of worship in the Andavan tradition is the divine sandals of Sri Ranganatha known simply as Rangantha-padukas.
