List of fictional galactic communities

This is a list of fictional galactic communities who are space-faring, in contact with one or more space-faring civilizations or are part of a larger government, coalition, republic, organization or alliance of two or more separate space-faring civilizations. They may be large galactic polities, or smaller ones. In ufology and some New Age religions there are claims and speculations of the existence of a Galactic Federation, but no evidence has ever been presented to prove its existence beyond an imaginary concept.
