• In general, Jains do not worship Ganesh as a central or divine figure. The core Jain worship is directed toward the Tirthankaras and liberated souls. Some Jain people may show reverence in cultural contexts, but Ganesh is not a standard object of Jain spiritual practice. This aligns with Jain teachings that emphasize the path to liberation through the Tirthankaras, not through Hindu gods. ( jainknowledge.com)

• There is a tradition difference:

- Śvetāmbara Jains: Ganapati is propitiated at the beginning of auspicious acts and ceremonies in some communities, and there are procedures described for installing Ganapati images in certain texts. However, this is a ritual practice rooted in local custom rather than core Jain worship of the divine. ( jainknowledge.com) - Digambara Jains: Ganapati is not commonly integrated into their temple worship or canonical rites; the iconography and texts of Digambara sources focus on the Jina s and Jain cosmology rather than Ganesh.
