Frank Miller (born January 27, 1957) is an American comic book artist, comic book writer, and screenwriter known for his comic book stories and graphic novels such as Daredevil, for which he created the character Elektra, and subsequent Daredevil: Born Again, The Dark Knight Returns, Batman: Year One, Sin City, and 300.

Miller is noted for combining film noir and manga influences in his comic art creations. He said: "I realized when I started Sin City that I found American and English comics to be too wordy, too constipated, and Japanese comics to be too empty. So I was attempting to do a hybrid." Miller has received every major comic book industry award, and in 2015 he was inducted into the Will Eisner Award Hall of Fame.

Miller's feature film work includes writing the scripts for the 1990s science fiction films RoboCop 2 and RoboCop 3, sharing directing duties with Robert Rodriguez on Sin City and Sin City: A Dame to Kill For, producing the film 300, and directing the big screen adaptation of The Spirit. Sin City earned a Palme d'Or nomination.
