Poigai Alvar was one of the twelve Alvar saints of South India, who are known for their affiliation to Vaishnava tradition of Hinduism. The verses of Alvars are compiled as Nalayira Divya Prabandham and the 108 temples revered are classified as Divya Desam. Poigai is one of the three principal Alvars, with the other two being Bhoothath Alvar and Peyalvar, collectively called Mutalamalvargal, who are regarded to be born out of divinity. Poigai composed hundred verses that are classified as Mutal Tiruvantati, and his composition is set in the antati style, in which the ending syllable is the starting one for the next verse.

The Alvars were the Tamil poet-saints of South India who espoused bhakti (devotion) to the Hindu preserver deity Vishnu, in their songs of longing, ecstasy, and service. They are venerated in Vaishnavism, which regards Vishnu as the Ultimate Reality.
