No. In Jain tradition, Krishna Bhagwan is not considered a Jain in the sense of being a Tirthankar, monk, or follower of Jain vows.

In Jain scriptures, Krishna is regarded as a Vasudev and a महान historical figure connected with the Harivansh lineage. He is also described as the cousin of Neminath Bhagwan. But being related to a Tirthankar does not make someone Jain.

So the correct understanding is:

• Neminath Bhagwan — a Tirthankar
• Krishna Bhagwan — a great figure mentioned in Jain tradition, but not a Jain Tirthankar

Jain tradition respects Krishna’s place in history, but he is not counted among Jain spiritual leaders.
