In Jainism, there is no fixed or required varna like in the Hindu system of Brahmin–Kshatriya–Vaishya–Shudra.

Key points:

• Varna is a Hindu social concept, not a Jain religious requirement.
• Jain Dharma does not give any spiritual importance to birth, caste, or varna.

- Every jiva (soul) is equal and can attain moksha through right faith, right knowledge, and right conduct. ( jainknowledge.com)

• Historically, Jains have come from different social backgrounds (some with Brahmin, Kshatriya, Vaishya, etc. origins), but:

- Once someone follows Jain Dharma, they are primarily known as Jain (Śrāvaka/Śrāvikā for lay followers, and Sādhu/Sādhvī for monks/nuns) – not by varna.

• Both Digambar and Shwetambar traditions agree:

- Spiritual progress does not depend on varna or caste, only on personal conduct and karma. ( jainknowledge.com)

So, if someone asks, “Jains come under which varna?”, the most correct Jain answer is:

> Jains do not belong to any particular varna; Jain Dharma does not recognize birth‑based varna as a condition for spiritual status. A follower is simply called a Jain.
