Swaminarayan, (3 April 1781 – 1 June 1830), also known as Sahajanand Swami, is the central figure in a modern sect of Hinduism known as the Swaminarayan Hinduism, a form of Vaishnavism.[Swaminarayan was born Ghanshyam Pande in Chhapaiya, Uttar Pradesh, India in 1781. In 1792, he began a seven year pilgrimage across India, adopting the name Nilkanth Varni. He settled in the state of Gujarat around 1799. In 1800, he was initiated into the Uddhav Sampraday by his guru, Ramanand Swami, and was given the name Sahajanand Swami. In 1802, his guru handed over the leadership of the Uddhav Sampraday to him before his death. Sahajanand Swami held a gathering and taught the Swaminarayan mantra. From this point onwards, he was known as Swaminarayan and within the sect, he is regarded as an incarnation of God, Purushottama, or is venerated as an incarnation of Narayana from the Nara-Narayana deity pair by his followers. The Uddhav Sampraday became known as the Swaminarayan Sampraday.

Swaminarayan developed a good relationship with the British Imperial Government. He had followers not only from Hindu denominations, but also from Islam and Zoroastrianism. He built six temples in his lifetime and appointed 500 paramhansas to spread his philosophy. In 1826, Swaminarayan wrote the Shikshapatri, a book of social principles. He died on 1 June 1830 and was cremated according to Hindu rites in Gadhada, Gujarat. Before his death, Swaminarayan appointed his adopted nephews as acharyas to head the two dioceses of Swaminarayan Sampraday.

Swaminarayan is also remembered within the sect for undertaking reforms for women and the poor, performing yagnas or fire sacrifices on a large scale as well as performing miracles. He has been criticised by historians and religious leaders who questioned the acceptance of Swaminarayan as God. Swaminarayan had an estimated 1.8 million followers when he died. Currently, his following is estimated between 5 and 20 million.
