"Man of Steel" is one of the bynames of the superhero Superman, and gives the title to several works featuring him (either that, or you were looking for Josef Stalin):
- The Man of Steel: The comic book miniseries that introduced the Post-Crisis version of Superman.
- Lex Luthor: Man of Steel: A graphic novel showing the world from the viewpoint of Superman's archenemy Lex Luthor,
- Man of Steel: The 2013 reboot of the Superman film series starring Henry Cavill as Superman, and first film of the DC Extended Universe.
- The character Steel, who originally took on the name "Man of Steel" after Superman was killed by Doomsday. After he was revived, it was shortened to Steel to avoid confusion.
- Man of Steel (2018), the six issue mini-series by Brian Michael Bendis
