The International Ultramarine Corps, formerly the Ultramarine Corps, is a fictional team of superheroes published by DC Comics. They first appeared in DC One Million #2 (November 1998), and were created by Grant Morrison and Howard Porter.

The Corps was created by the US federal government as a government-sponsored group of superhumans, in contrast to the more independent Justice League. Led by General Wade Eiling, the original members of the team were Flow, 4-D, Pulse 8 and Warmaker One.

During a fight with the JLA, the UMC realised that Eiling was dangerously insane and that they were on the wrong side; they then sided with the League against their leader.

Having developed a mistrust of governments, the Corps subsequently declared themselves independent of any and all nations and built a free-floating city in which to dwell, which they named Superbia and set in the air above the ruins of Montevideo. They called for other disaffected superheroes to join them in their city, receiving responses from around the globe. However, the total population and demographics of Superbia are unknown.

International Ultramarines Corps has not been a contender in any CBUB matches.
