The Solar Belt Confederation was an interplanetary government within the Sol system that was extant at least in the early 22nd century.

Its member states included those on the four largest asteroids in the region between Mars and Jupiter: Vesta, Ceres, Pallas, and Eros. In 2155, the population of the Confederation was 26,700 beings, mostly Human. (The Romulan War)

The Confederation's status after the establishment of either the Coalition of Planets or the United Federation of Planets was not revealed.
