Iron Munro, real name Arn Munro, is a superhero character appearing in American comic books published by DC Comics. Roy Thomas created the character in 1987 for Young All-Stars. He largely served to replace Superman in stories set during World War II after the Crisis on Infinite Earths storyline eliminated continuities in which Superman was active in this period.

After DC cancelled Thomas' World War II-set comic All-Star Squadron in the wake of Crisis on Infinite Earths, the company charged him with writing a followup series with a new superhero team, Young All-Stars. Iron Munro was one of several new characters Thomas created as analogues for popular superheroes written out of the continuity; he stood in for Superman, with comparable powers and appearance. He was inspired by two 1930s pulp fiction characters who in turn prefigured Superman: John W. Campbell's science fiction hero Aarn Munro, who appeared in comics as "Iron Munro", and Hugo Danner, the protagonist of Philip Wylie's 1930 novel Gladiator, who had powers similar to Superman's and is sometimes seen as an inspiration.

Young All-Stars did not achieve the popularity All-Star Squadron, which had featured better known characters from the Golden Age of Comic Books. The series was cancelled in 1989. However, Iron Munro continues to make occasional appearances in DC Comics.

From 1981 to 1987, Roy Thomas wrote DC Comics' popular series All-Star Squadron, set on Earth-Two, a parallel universe based on the company's characters of the 1940s Golden Age of Comic Books. All-Star Squadron depicts a team of Earth-Two versions of characters like Superman, Batman, and Wonder Woman fighting in World War II. In 1985, DC launched the Crisis on Infinite Earths crossover storyline, which ultimately eliminated the company's Multiverse of parallel worlds in favor of a new unified continuity. This removed Superman and others from the World War II setting, and DC cancelled All-Star Squadron in 1987.
