Yes, as a Hindu you can marry a Jain girl.

From the Jain dharmic point of view:

• Jain scriptures do not forbid marriage with a non‑Jain. Marriage is seen more as a social/householder arrangement than a religious sacrament. ( jainknowledge.com)
• So, a Hindu boy and a Jain girl can marry, provided both live with mutual respect and follow basic ethical principles like ahimsa (non‑violence), truthfulness, fidelity, and simple living. ( jainknowledge.com)

What you both should discuss clearly before marriage:

1. Food and lifestyle

- Many Jains are very strict vegetarians (no meat, fish, eggs; often no alcohol, sometimes no root vegetables, no night‑eating). - You should be ready to respect this fully at least inside the home.

1. Religious practice

- Will she (and possibly you) do Jain puja, Navkar Mantra, Paryushan/Dashlakshan, fasting, etc.? - Are you comfortable supporting that?

1. Children

- How will children be brought up: mainly Jain, mainly Hindu, or exposed to both? - Which festivals, temples, and teachings will be primary?

1. Family expectations

- Some Jain families strongly prefer a Jain spouse; others are open if Jain values at home are protected. So family conversation is important. ( jainknowledge.com)

From Jain dharma’s side, the key point is: If you sincerely respect her Jain values, especially non‑violence and simple living, and both of you are clear and honest about future life (diet, festivals, kids), then such a marriage is acceptable.
