The Legion of Super-Heroes is a fictional superhero team appearing in American comic books published by DC Comics. Created by writer Otto Binder and artist Al Plastino, the Legion is a group of superpowered beings living in the 30th and 31st centuries of the DC Comics Universe, and first appears in Adventure Comics #247 (April 1958).

Initially, the team was closely associated with the original Superboy character (Superman when he was a teenager), and was portrayed as a group of time travelers. Later, the Legion's origin and back story were fleshed out, and the group was given its own monthly comic. Eventually, Superboy was removed from the team altogether and appeared only as an occasional guest star.

The team has undergone two major reboots during its run. The original version was replaced with a new rebooted version following the events of the "Zero Hour" storyline in 1994 and another rebooted team was introduced in 2004. A fourth version of the team, nearly identical to the original version, was introduced in 2007. In 2019, DC announced a new series written by Brian Michael Bendis and drawn by Ryan Sook.
