In Jainism, a "Vasudeva" is a universal monarch or a heroic figure who appears in every time cycle (Avasarpini and Utsarpini). Each cycle features nine Vasudevas, who play significant roles in Jain universal history.

The most well-known Vasudeva is Shri Krishna, who is considered the 8th Vasudeva of the current Avasarpini (descending half-cycle). His elder brother, Baladeva (Balarama), and their adversary, Prativasudeva (Jarasandha or Kansa), are also prominent figures in Jain narratives.

Here is the list of the nine Vasudevas according to Jain tradition (in the current Avasarpini):

1. Triprishta Vasudeva
2. Dwiprishta Vasudeva
3. Sagar Vasudeva
4. Sanmati Vasudeva
5. Shanti Vasudeva
6. Kunthu Vasudeva
7. Ara Vasudeva
8. Padma (Krishna) Vasudeva
9. Narayana (Lakshmana or Neminatha's cousin, in some texts)

Among these, Padma (Krishna) is the most renowned.

To summarize: The name of the most famous Vasudeva in Jainism is Padma, also known as Shri Krishna.
