In Jainism, Shrimad Rajchandra (1867–1901) is revered as a great spiritual teacher and philosopher, especially among followers of the Jain Shwetambar tradition and some lay communities. He did not establish a formal sect, but his teachings have inspired many groups and spiritual leaders.

Currently, there is no official or universally recognized "biggest devotee" of Shrimad Rajchandra, as devotion is a personal spiritual matter and not measured publicly in Jain tradition. However, several organizations and individuals continue to spread his teachings. The Shrimad Rajchandra Mission Dharampur, led by Pujya Gurudevshri Rakeshbhai Jhaveri, is one of the most prominent groups dedicated to his philosophy and spiritual guidance. Followers of this mission and similar groups consider themselves devoted to Shrimad Rajchandra's teachings.

In Jainism, rather than focusing on identifying the "biggest devotee," emphasis is placed on following the teachings and striving for self-realization and liberation, as exemplified by Shrimad Rajchandra’s own life and message.
