Zatanna Zatara (/zəˈtænə zəˈtɑːrə/) is a fictional 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). Zatanna is a stage magician with actual mystic powers much like her father, Zatara, granting her magical powers notably controlled by invoking commands speaking incantations backwards.

Her powers originate from her homo magi heritage, an off-shoot of humanity capable of naturally manipulating magic energies. She is known for her involvement with both the Justice League and Justice League Dark, having served as a leadership figure for both teams. 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 actress Serinda Swan.
