This is a list of supervillains appearing in DC Comics who are or have been enemies of the superhero Superman. Several of Superman's opponents (most notably Darkseid and Brainiac) are or have been foes of the Justice League as well. Unlike most heroes, Superman's adversaries exist in every known capacity; humans, metahumans, androids, sorcerers, empowered animals, other aliens (such as Kryptonians), mythical/supernatural creatures, corrupt doppelgängers of himself (imposters, clones, or parallel universe counterparts), interdimensional beings (Mr. Mxyzpltk, Vyndktvx), and even deities.
