The Outer Colonies were planets controlled by the Terran Confederacy. Despite a similar naming, they were a separate group of planets from the Fringe Worlds,[1] but overlapped astrogeographically. For instance, Mar Sara was both a Fringe World and Outer Colony.[2]

By 2478, revolts were common among the Outer Colonies and were steadily growing in number.[1] By 2499, there is evidence that the Confederacy sought to discourage settlement of the Outer Colonies.[2]

The Outer Colonies continued to be controlled by the Terran Dominion well into the reign of Emperor Valerian Mengsk. They were represented by Senator Joss Brogan, who was arrested after hiding his criminal record.[3]

Some of the Outer Colonies such as Bountiful came under attack by the feral zerg during the early stages of the Defenders of Man Insurgency. These were repelled by the Defenders of Man, who had engineered the attacks to weaken the people's faith in Valerian Mengsk's rule.[4]
