The Laksmi Narayan Dev Gadi is one of the two gadis (diocese) that together form the Swaminarayan Sampradaya. It is headquartered at the Shri Swaminarayan Mandir, Vadtal and controls the Dakshin Vibhag Lekh.

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.
