Sri Vaishnavism (Sanskrit: श्रीवैष्णवसम्प्रदाय, romanized: Śrīvaiṣṇavasampradāya) is a denomination within the Vaishnavism tradition of Hinduism, predominantly practiced in South India. The name refers to goddess Lakshmi (also known as Sri), as well as a prefix that means "sacred, revered", and the god Vishnu, who are together revered in this tradition.
The tradition traces its roots to the ancient Vedas and Pancharatra texts, popularised by the Alvars and their canon, the Naalayira Divya Prabandham. The founding of Sri Vaishnavism is traditionally attributed to Nathamuni of the 10th century CE; its central philosopher has been Ramanuja of the 11th century, who developed the Vishishtadvaita ("qualified non-dualism") Vedanta sub-school of Hindu philosophy. The tradition split into two denominations around the 16th century. The Vadakalai or uttarakalārya sect emphasize the Vedas and follow the doctrine of Vedanta Desika, whereas the Tenkalai or dakṣiṇakalārya sect emphasize the Naalayira Divya Prabandham follow the principles of Manavala Mamunigal. The Telugu Brahmins of the Sri Vaishnava tradition form a single distinct sect called the Andhra Vaishnavas, and are not divided into the Vadakalai and Tenkalai denominations, unlike the Tamil Iyengars.
