Starfire is a superheroine created by Marv Wolfman and George Pérez appearing in American comic books created by DC Comics. She debuted in a preview story inserted within DC Comics Presents #26 (October, 1980). Since the character's introduction, Starfire has been a major recurring character in Teen Titans and various other iterations of the team, sometimes depicted as the team's leader, and a significant love interest for Dick Grayson.

Within the main continuity of the DC Universe, her origin is revealed to be Princess Koriand'r, an alien princess from the planet Tamaran and heir to the throne until she was ousted in a coup by her elder sister, Komand'r (also known as Blackfire), who sold her into slavery. Subjected to torture and sexual exploitation, Koriand'r was also subjected to experiments performed by Psion scientists, which gave her additional powers. Escaping her captors, she found herself on Earth and befriended the Teen Titans, becoming a long-lasting member of the team. The character has appeared on several other teams, including the Outsiders, Outlaws, and Justice League Odyssey. While on Earth, the character has been depicted as a model under the alias Kory Anders, occasionally the leader of the Teen Titans, and was the principal of Teen Titans Academy during a period in which the Titans help trained future superheroes of the DC Universe.

Starfire has been featured in various media outside comic books. Within television, she is notably voiced by Hynden Walch in the animated series Teen Titans and Teen Titans Go!. Kari Wahlgren voices the character in the DC Animated Movie Universe, Injustice 2, and Lego DC Super-Villains.

Created by Marv Wolfman and George Pérez, Starfire first appeared in a in DC Comics Presents #26 (October 1980), in a preview story heralding a new incarnation of the Teen Titans that also introduced Cyborg and Raven. The new series, The New Teen Titans, debuted in November 1980, and the Teen Titans subsequently became DC Comics' most popular superhero team of its day. Wolfman named the character as a pun on the word coriander.

Pérez said of his design for Starfire:

...I figured based on the description, was Red Sonja in outer space, so she ended up having a visual cue from that. When Joe Orlando passed by and saw the character sketches he suggested that maybe her hair should be longer. That I took to the ninth degree and gave her the Mighty Mouse contrail.

Princess Koriand'r was born on the planet Tamaran, located in the Vega system. Koriand'r was the second of three children. She and her brother Ryand'r are placed first in the line of succession after their older sister Komand'r is crippled by a childhood illness that robs her of the ability to fly. Shunned and embittered by Tamaran's society, Komand'r allies with the Citadel and helps them conquer Tamaran.

Koriand'r is captured by the Citadel for six years and subjected to physical and emotional torture and sexual abuse. She and Komand'r are both captured by the Psions, who experiment on them and test their ability to absorb solar energy. Both sisters gain the ability to project blasts of solar energy, referred to as "starbolts". Koriand'r escapes and eventually finds her way to Earth, where she gains the help of the Teen Titans.
