The Joker technically doesn’t have one single, universally agreed “real” name, but the most recent mainstream DC Comics answer is Jack Oswald White in core continuity, while other famous versions call him Jack Napier or give him completely different identities.

Quick Scoop

  • In most classic Batman stories, the Joker’s real identity is deliberately left a mystery, which is part of what makes him so unsettling.
  • DC Comics officially revealed a main-universe name, Jack Oswald White , in the 2022 series Flashpoint Beyond and Batman: Three Jokers.
  • In Tim Burton’s 1989 Batman movie (and related tie‑ins), he’s a mobster named Jack Napier , a name that became hugely popular with fans.
  • Other adaptations invent different names, like Arthur Fleck in the 2019 Joker film, and various comics and games use aliases such as “Jack White” or “Joe Kerr.”
  • Creators have often said the mystery is intentional and that locking him into one tidy origin would make him less interesting.

So, what’s the “real” answer?

If you’re talking about:

  1. Current main DC Comics canon → Jack Oswald White.
  1. Most famous movie-era name → Jack Napier.
  1. Overall Batman mythos → His true name is meant to be uncertain, with multiple conflicting “real names” depending on the universe or adaptation.

The safest way to put it: the Joker’s “real name” changes with the story, and the ambiguity is on purpose, not a mistake.

TL;DR: In modern DC canon his name is Jack Oswald White, but across movies, comics, and games he’s also famously Jack Napier—and in many stories, he’s officially just an unnerving, nameless mystery.
