Michael Owen Rosenbaum (born July 11, 1972 in Oceanside, New York) is an American actor and voice actor. As an on-screen actor, he's best known for playing Lex Luthor on Smallville, Adam/Adina in Sorority Boys, Kip in Kickin' It Old School, and Dutch Nilbog in the short-lived Breaking In. As a voice actor, he's best known as the voice of the Wally West incarnation of The Flash in Justice League (replacing Charlie Schlatter, who voiced him on Superman: The Animated Series), Agent West in The Zeta Project, and Nick Carlyle in Lollipop Chainsaw.
He returned to voice the Flash in Justice League: Doom, this time playing Wally West's uncle and predecessor, Barry Allen—mirroring his predecessor as DCAU!Wally, Charlie Schlatter, who voiced Barry on The Batmannote . He'd later voice Barry in Infinite Crisis and LEGO DC Super-Villains.
These days, he hosts a podcast called Inside of You, wherein he interviews various celebrities across the entertainment industry about themselves and their careers, mostly actors.

Tropes associated with Michael Rosenbaum:
- Comic-Book Fantasy Casting: Ghoul in Batman Beyond: Return of the Joker and Deadshot in Justice League were based on impressions Rosenbaum did of Christopher Walken and Kevin Spacey respectively.
- Dyeing for Your Art: He had his head shaved to play Luthor on Smallville.
- Directed by Cast Member: He directed the Smallville episode "Freak".
- Mean Character, Nice Actor: It can be shocking to fans who only know him as the paranoid and cold Lex Luthor, but Rosenbaum is generally quite laid back and jocular in interviews, and especially on his podcast.
- Role Reprise: Unlike most of the rest of the League and 3/7 of the Legion of Doom in Justice League: Doom, this was averted as the Flash there was Barry Allen, not Wally West. Played straight in Infinite Crisis and LEGO DC Super-Villains, though, because of his voicing Barry in Doom.
- What Could Have Been:
- He screen-tested for the role of Peter Quill in the Marvel Cinematic Universe before the casting of Chris Pratt. He would eventually go on to portray Martinex in Guardians of the Galaxy Vol. 2.
- He was offered an unspecified role in The Suicide Squad, but turned down the offer due to complications with his neck surgery at the time.
- The Arrowverse crew asked him to reprise his Smallville role as Lex Luthor for Crisis On Infinite Earths, but due to a combination to the "Writing by the Seat of Your Pants" approach taken and the fact they asked him about this while he was visiting a sick relative, he turned them down.
