Bochasanwasi Akshar Purushottam Swaminarayan Sanstha is a Hindu denomination within the Swaminarayan Sampradaya. It was formed in 1905 by Yagnapurushdas following his conviction that Swaminarayan remained present on earth through a lineage of gurus starting with Gunatitanand Swami. As of August 2016, Mahant Swami Maharaj is the 6th guru and president of BAPS.

The Swaminarayan Sampradaya, also known as Swaminarayan Hinduism and Swaminarayan movement, is a Hindu Vaishnava sampradaya rooted in Ramanuja's Vishishtadvaita, characterized by the worship of its charismatic founder Sahajanand Swami, better known as Swaminarayan (1781–1830), as an avatar of Krishna or as the highest manifestation of Purushottam, the supreme God. According to the tradition's lore, both the religious group and Sahajanand Swami became known as Swaminarayan after the Swaminarayan mantra, which is a compound of two Sanskrit words, swami and Narayan.
