Yes, Ram and Krishna are part of Jain tradition, but they are not Tirthankars.

In Jainism:

• Sri Ram is revered as an ideal and noble figure, often identified with Baladeva in Jain narratives.
• Sri Krishna is also included in Jain cosmology and stories, often identified as Vasudeva.
• Their lives are described differently in Jain texts than in Hindu texts.
• They are not worshipped as liberated Tirthankars in Jain Dharma.

So, in short:

• Part of Jain literature and tradition: Yes
• Tirthankar: No
• Central objects of Jain worship: No

Jainism respects them as important historical or legendary figures within its own narrative framework, while the highest spiritual guides in Jainism are the 24 Tirthankars.
