Short answer: Yes, a person can still be Jain even if they worship Hindu gods.

Key points:

• Jainism defines being Jain by following its path and vows (non-violence, truth, non-stealing, celibacy or right conduct for householders, non-attachment, and right faith). Worship of Hindu gods does not by itself negate Jain identity.
• Many people in India and elsewhere blend practices from different traditions. In Jain communities, some Jains may honor Hindu deities or participate in Hindu rituals while still adhering to Jain ethics and the path of liberation.
• There are differences between Digambar and Shwetambar traditions in certain practices and interpretations, but neither tradition makes mere devotion to other gods the determinant of who is Jain. The core question is adherence to Jain principles and the pursuit of right conduct, knowledge, and faith.

Note: If you’re asking in a specific community or temple context, the local tradition might have particular expectations about rituals or deities.
