In Jainism, the mother of all Vasudevas is named Devaki.

According to Jain universal history, Vasudevas are heroic figures who appear in each half-cycle of time (Avasarpini and Utsarpini). In the current Avasarpini, there are nine Vasudevas. For all these Vasudevas, their mother is described as Devaki (also sometimes referred to as Devananda in some Jain texts).

Their father is traditionally named Vasudeva or Vasudevah.
