Gil Kane (/dʒɪl keɪn/, Latvian: Džils Keins; born Eli Katz /kæts/; April 6, 1926 – January 31, 2000) was a Latvian-born American comics artist whose career spanned the 1940s to the 1990s and virtually every major comics company and character.

Kane co-created the modern-day versions of the superheroes Green Lantern and the Atom for DC Comics, and co-created Iron Fist and Adam Warlock with Roy Thomas for Marvel Comics. He was involved in the anti-drug storyline in The Amazing Spider-Man #96–98, which, at the behest of the U.S. Department of Health, Education, and Welfare, bucked the then-prevalent Comics Code Authority to depict drug abuse, and ultimately spurred an update of the Code. Kane additionally pioneered an early graphic novel prototype, His Name Is... Savage, in 1968, and a seminal graphic novel, Blackmark, in 1971.

In 1997, he was inducted into both the Will Eisner Comic Book Hall of Fame and the Harvey Award Jack Kirby Hall of Fame.
