Yes. In Jainism, there are devas and devis—celestial beings who live in heavenly realms. They are sometimes loosely called “demigods” in English, but that is not a perfect equivalent.

Key point in Jainism:

• They are not creators of the universe.
• They are not supreme or all-powerful.
• They are still bound by karma and rebirth.
• Their lives in heaven are temporary, not liberation.

So, in Jain understanding, celestial beings exist, but they are not divine in the absolute sense. Only a soul that has destroyed all karma and attained moksha becomes completely liberated.
