Random Tiefling Name Generator

The Player's Handbook lists male Infernal names (Akmenos, Amnon, Barakas, Damakos, Ekemon, Iados, Kairon, Leucis, Melech, Mordai, Morthos, Pelaios, Skamos, Therai), female Infernal names (Akta, Anakis, Bryseis, Criella, Damaia, Ea, Kallista, Lerissa, Makaria, Nemeia, Orianna, Phelaia, Rieta) and virtue names such as Art, Carrion, Creed, Glory, Hope, Poetry, Reverence, Sorrow and Temerity. All of them are included here.

Not by Infernal tradition, but many adopt one from the human culture they grew up in, and Baldur's Gate 3 and Critical Role characters like Mollymauk Tealeaf show how well that works. A surname is optional and usually says more about where the tiefling was raised than about their bloodline.

A virtue name is a word for an ideal, emotion or concept that a tiefling takes as their personal name, often to signal a break with their fiendish heritage. Canon examples include Hope, Quest, Random, Reverence and Torment; the name is meant to be aspirational, ironic or both.

Yes. The naming conventions and the original names here are free to use; a handful of famous character names from Baldur's Gate 3 and Critical Role are included for reference and are best treated as inspiration rather than lifted for commercial work.
