Who Killed Batman's Parents?
The answer in brief
Joe Chill, in the canonical version of the comics: an armed and desperate street criminal who encounters the family leaving the theater, demands their valuables, and shoots them.

However, depending on the era, films, or animated series, this designated culprit has changed faces.

But depending on the era, comics, films, or animated adaptations, the identity of the murderer has sometimes changed, offering varied and nuanced interpretations.

Joe Chill: The Canonical Murderer
In the most prevalent version of the comics, the person responsible for the murder of Thomas and Martha Wayne is a petty street criminal named Joe Chill. This armed and desperate robber encounters the Wayne family as they leave a theater and attempts to steal their belongings. The situation escalates, and Chill coldly shoots Bruce's parents, leaving the child alone in the alley.

This murder is not premeditated by a grand supervillain, but the result of chance and Gotham's mundane criminality. It is this detail that makes the tragedy even more striking: Batman was not born of a conspiracy, but of the ordinary chaos of a city consumed by fear. The symbolism is strong: any criminal can break a life, and it is this injustice that Bruce Wayne will fight his entire life.
Over the years, some versions have even shown adult Bruce encountering Joe Chill. In some adaptations, he confronts him directly, sometimes revealing his secret identity. In others, Chill is eliminated by criminals who fear he might reveal having killed the future Dark Knight's parents. Regardless, his name remains etched in Gotham's legend.

When Adaptations Change the Murderer
While in the canonical comics Joe Chill is indeed the Wayne family's assassin, some adaptations have chosen to alter this origin. This narrative choice allows for a more personal dimension to Bruce Wayne's foundational tragedy, but also links his story to that of his future enemies.
In Tim Burton's 1989 film Batman, it is the Joker – then named Jack Napier – who is identified as the murderer. This revelation adds a tragic depth to their rivalry: the Joker created Batman, and Batman created the Joker.

Other narratives have sometimes suggested that the murder might have been ordered by Gotham's criminal powers, such as Carmine Falcone or even the future Penguin. These versions highlight the idea that Bruce Wayne's fate is linked to the city's major mafia families, emphasizing the corruption that plagues Gotham.
Finally, some animated series and adaptations have chosen to keep the killer unknown, reinforcing the universal nature of the tragedy. Regardless of the culprit: it is the act itself that shaped Batman.
