Zatanna Zatara (/zəˈtænə zəˈtɑːrə/), known mononymously as Zatanna, is a superhero appearing in American comic books published by DC Comics. The character was created by Gardner Fox and Murphy Anderson, and first appeared in Hawkman #4 (November 1964). Throughout the character's history, Zatanna is depicted as one of DC Comics' most well-regarded supernatural superheroes.

The character is depicted as a renowned sorceress belonging to the fictional Homo magi race, a subset of humans endowed with innate potential to manipulate magic. She is also the daughter of Giovanni Zatara and Sindella, the former a renowned stage magician and sorcerer whom she models herself after and the latter whose lineage connects her to the royal line of Atlantis. Zatanna balances her life as an international celebrity stage magician and superhero who often fights against the forces of evil and serves as both a mystic consultant and a notable member of several teams such as the Justice League, Justice League Dark, and the Sentinels of Magic. Within the DC Universe, she is often regarded as one of the most powerful magic users.

Zatanna has appeared in several different media adaptations, including appearing in several television series in the DC Animated Universe, notably voiced by Julie Brown and Jennifer Hale. She has also appeared as a recurring character in the final three seasons of Smallville, portrayed by Serinda Swan. A younger version of the character appears in Young Justice and Justice League Action, voiced by Lacey Chabert, and DC Super Hero Girls, voiced by Kari Wahlgren.

Created by writer Gardner Fox and artist Murphy Anderson, Zatanna first appeared in Hawkman #4 (November 1964). When she is introduced, she is on a quest to find her father Zatara who made his first appearance in Action Comics #1 but had not been published regularly for several years. The storyline crossed multiple comics published by DC at the time, culminating in issues of Justice League of America, also written by Fox.

In her original origin, Zatanna was born to human Giovanni Zatara and Homo magi Sindella, inheriting her mother's natural affinity for magical powers. Six months after her birth, her mother disappeared and was presumably dead, leading her to be raised by her father. Growing up to be a stage magician with genuine magical powers and modelling herself similarly to her father, Zatara later mysteriously disappears, leading her to travel abroad to perfect her magical craft while searching for her father. Unknown to her, the details of her parents' disappearance were revealed over time; her mother would later return to her people, a clan of Homo magi known as the "Hidden Ones" and her father was cursed by evil sorceress Allura that would kill both himself and his daughter should he see her again, leading him to reluctantly distance himself from her.

In her debut, she is introduced during her quest to find her father, first encountering Hawkman and Hawkgirl. During her quest, she encounters various other superheroes such as Batman and Robin (wherein she was disguised as a witch under the control of villain the Outsider) and teams up with others including the Atom, Green Lantern, and the Elongated Man. Eventually, she learns her father's fate and finds him in the mystic dimension of Kharma and encounters the evil Allura, where her good counterpart forces her to lift the curse, reuniting father and daughter after 2 decades.

Not long after, she is elected to become a valued member of the Justice League of America, although in her tenure her powers were originally diminished, allowing her only to control natural forces. Both her mother and her true background is later revealed to her, when Zatanna learns the cause of her mother's disappearance and reason for faking her death: possessing a "medula jewel" within her brain, it acted as a source of power for her clan of the Hidden Ones. Fearing her clan would hunt down her daughter, who also inherited a medulla jewel, she telepathically warns her, with Sindella's magic having the odd side-effect of transforming her costume to one resembling her own. With her father and JLA, they meet Sindella, where she explains her disappearances and sacrifices herself to save Zatanna and Zatara from captivity.

After the Crisis on Infinite Earth crossover event, much of Zatanna's history remained the same although several changes came about to her background; her new history reinforced her father's disappearance to have taken place when she was eighteen years old. At some point prior to her father's death, a young Zatanna also met John Constantine, with whom she once engaged in tantric sex. Her father later became aware of their relationship, disapproving of Constantine.
