Here are common Jain names that start with the letter D (both male and female):

• Male

- Daman - Dinesh - Dipak / Dipendra - Divyesh - Dharam - Dhiraj - Deepak - Devendra (note: commonly used in broader Indian names) - Dhaval - Durgesh

• Female

- Damini - Darshana - Devika - Divya - Dipali - Diksha (often used in Jain contexts) - Disha

If you’d like, I can provide meanings (arth) for any specific names or suggest names tailored to a particular tradition (Digambara vs. Śvetāmbara).
