Batman / Batman Joker

Does Joker Know Who Batman Is in the Comics?

The relationship between Batman and Joker is one of the most iconic rivalries in the comic book world. One question that often comes up is whether or not Joker knows Batman’s true identity. It is a topic of much debate among fans and has been explored in various comic book storylines over the years.

Early Years

In the early days of Batman comics, it was commonly believed that Joker did not know Batman’s true identity. He was simply obsessed with causing chaos and destruction in Gotham City, and Batman was his main Target. However, as the comics evolved, so did their relationship.

The Killing Joke

One of the most famous storylines involving Joker and Batman is “The Killing Joke,” written by Alan Moore. In this story, Joker attempts to prove that anyone can be driven insane after one bad day. He shoots Barbara Gordon (aka Batgirl) and kidnaps Commissioner Gordon, subjecting him to a series of psychological torments.

During their confrontation, Joker admits that he knows Batman’s true identity but doesn’t care about it. He believes that their relationship is more important than any secret identity.

Other Storylines

Other storylines have explored this theme as well. In “Batman: Death of the Family,” Joker claims to know all of Batman’s secrets but doesn’t reveal them to anyone else. In “Batman: Endgame,” he hints at knowing who Batman really is but again doesn’t reveal it explicitly.

The Conclusion?

So, does Joker know who Batman really is? The answer depends on the storyline!

There have been instances where he has known and others where he hasn’t. However, even when he does know, he doesn’t seem to care about revealing it to anyone else or using it against Batman.

In some ways, this ambiguity adds to the intrigue of their relationship. Batman and Joker are two sides of the same coin, and their dynamic is what makes them such compelling characters.


In conclusion, the question of whether or not Joker knows Batman’s true identity is a complex one. While there have been storylines where he does know, it ultimately doesn’t seem to matter in their ongoing rivalry. Batman and Joker will always be locked in a battle of wits and will continue to captivate readers for years to come.
