Guardian (James Jacob "Jim" Harper and Mal Duncan) are DC Comics superheroes introduced in April 1942 by writer/artist Joe Simon and artist Jack Kirby.

Guardian resembles the earlier Kirby and Simon character Captain America (first published 13 months earlier by Marvel Comics), as he had no super powers and carried an indestructible shield. When Kirby returned to DC in 1970, he eventually re-established the character as a supporting one in the Superman franchise: as a clone of Jim Harper who was head of security for Project Cadmus.

In the Arrowverse series Supergirl, James Olsen, portrayed by Mehcad Brooks, became the superhero Guardian. Additionally, James Harper appeared in the first season as a marine colonel portrayed by Eddie McClintock. In the sixth season, Olsen’s sister Kelly Olsen (portrayed by Azie Tesfai) became known as the Golden Guardian.
