Two-Face (Harvey Dent) is a fictional supervillain appearing in American comic books published by DC Comics, commonly as an adversary of the superhero Batman. The character was created by Bill Finger and Bob Kane and first appeared in Detective Comics #66 (Aug. 1942). As one of Batman's most enduring enemies, Two-Face belongs to the collective of adversaries that make up Batman's rogues gallery.

Once an upstanding Gotham City District Attorney, Harvey Dent was hideously scarred on the left side of his face after a mob boss threw acidic chemicals at him during a court trial. He was subsequently driven insane and adopted the "Two-Face" persona, becoming a criminal obsessed with the number two and duality. In later years, writers have portrayed Two-Face's obsession with chance and fate as the result of schizophrenia, bipolar disorder, and dissociative identity disorder. He obsessively makes all important decisions by flipping his former lucky charm, a two-headed coin which was damaged on one side by the acid as well. The modern version is established as having once been a personal friend and ally of James Gordon and Batman.
