Answer

Yes, Modi can be found as a surname/community name among some Jains, especially in parts of Gujarat and Rajasthan.

However, in Jain Dharma, spiritual identity is not based on gotra in the same way as some other Indian traditions. Among Jains, people more commonly identify by:

• Jain sect such as Śvetāmbara or Digambara
• Gaccha / sampradāya in some traditions
• Family surname such as Shah, Mehta, Modi, etc.
• Community background such as Oswal, Porwal, Shrimali, etc.

Explanation

The word Modi is generally understood as a surname or occupational/community title, not necessarily a Jain religious category. Some people with the surname Modi are Jain, while others may belong to different communities or religions.

So, if someone asks “Is Modi gotra Jain?” the careful answer is:

• Modi is found among Jains.
• But Modi itself does not automatically prove someone is Jain.
• It is better understood as a surname/family name rather than a Jain gotra.

Takeaway

Yes, there are Jains with the surname Modi, but Jain identity is primarily connected with following Jain Dharma, Jain values, and Jain traditions—not merely with a surname or gotra.
