Thanos () is a fictional character appearing in American comic books published by Marvel Comics. Created by writer-artist Jim Starlin, the character first appeared in The Invincible Iron Man #55 (cover date February 1973). An Eternal–Deviant warlord from the moon Titan, Thanos is regarded as one of the most powerful beings in the Marvel Universe. Due to his genocidal tendencies, he has clashed with many heroes including the Avengers, the X-Men, the Fantastic Four, and the Guardians of the Galaxy.

In creating Thanos, Starlin drew inspiration from Jack Kirby's New Gods series for DC Comics, particularly the character of Darkseid. Thanos is usually portrayed as a villain, although many stories depict him as believing his actions to be justified. Perhaps the character's best-known storyline is The Infinity Gauntlet (1991), the culmination of several story arcs that see him gather the six Infinity Gems and use them to kill half of the universe's population, including many of its heroes, to woo Mistress Death, the living embodiment of death in the Marvel Universe. Although these events were later undone, the storyline has remained one of the most popular published by Marvel.

Debuting in the Bronze Age of comic books, the character has appeared in more than five decades of Marvel publications, as well as many media adaptations, including animated television series and video games.

In the Marvel Cinematic Universe, the character was first played by Damion Poitier in the film The Avengers (2012) and then by Josh Brolin in Guardians of the Galaxy (2014), Avengers: Age of Ultron (2015), Avengers: Infinity War (2018), Avengers: Endgame (2019), and the first season of the animated series What If...? (2021).

Creation Writer-artist Jim Starlin conceived of Thanos of Titan during college psychology classes and was inspired by Sigmund Freud's concept of human death drive, or Thanatos. As Starlin described:
