Yes, there are tantric and mantra-based traditions associated with Jainism, but they must be understood within Jain Dharma, not in the same way as non-Jain tantric systems.

In Jain tradition, you will find:

• Mantras for devotion, protection, and spiritual focus
• Yantras used in ritual worship in some traditions
• Vidyas and sacred recitations connected with Tirthankars, Yakshas, and Yakshinis
• Ritual practices that developed in later Jain culture

But the core Jain path remains:

• Right faith
• Right knowledge
• Right conduct
• Ahimsa
• Self-purification
• Liberation from karma

So, if by “Jain tantra” you mean esoteric ritual and mantra practices found in Jain tradition, then yes. If you mean a system that replaces Jain ethics or liberation path, then no—that would not be Jain Dharma.

In short: Jainism has tantric/ritual traditions, but its essence is still the path of आत्मशुद्धि, संयम, and मोक्ष.
