The Crime Syndicate of America is a team of evil counterparts to the Justice League living on an alternate Earth. In Pre-Crisis continuity, they lived on Earth-Three until their world and their universe were destroyed during Crisis on Infinite Earths. Their original membership included Johnny Quick, Owlman, Power Ring, Super-Woman, and Ultraman. Post-Crisis, they were reimagined first as the Thunderers and later as the Crime Syndicate of Amerika in the Antimatter Universe. There is also another counterpart in the 52 Multiverse named the Crime Society, evil counterparts to the Justice Society on Earth-3. The New 52 reboot introduces a new Crime Syndicate on Earth 3 in Trinity War. Each of these versions have their own differences.

The Crime Syndicate was created by Gardner Fox and Mike Sekowsky, first appearing in Justice League of America #29 (1964).
