Answer

Yes, there are Jains with the surname or community name “Thakur” in some regions, especially where “Thakur” is used as a family title, caste title, or local surname.

However, “Thakur Jain” is not a separate Jain sect like Śvetāmbara, Digambara, Sthānakavāsī, Terāpanth, etc.

Explanation

In Jain Dharma, a person’s religious identity is based on following Jain teachings such as:

• Ahimsa — non-violence
• Aparigraha — non-possessiveness
• Anekāntavāda — understanding many viewpoints
• Devotion to the Tirthankars
• Right faith, right knowledge, and right conduct

Surnames like Thakur, Shah, Jain, Doshi, Mehta, Gandhi, Lodha, Sethi, Singhi, etc., can vary by region and family history.

Takeaway

So, a person can be both Thakur by surname/community identity and Jain by religion, but “Thakur Jain” itself is not a distinct Jain religious sect.
