The Federation Alliance was an alliance of Alpha and Beta Quadrant powers led principally by the United Federation of Planets during the 24th century.

During the Dominion War the alliance was an accord between the Federation, Klingon Empire and the Romulan Star Empire to combat the Dominion forces in the Alpha Quadrant. The alliance was ultimately victorious, expelling the Dominion from the quadrant and occupying its former territories in the Cardassian Union. (DS9: "What You Leave Behind")

The Lyran Democrative Republic were de facto members of the Federation Alliance when they fought the Dominion at the Klingons' side. (RIS Bouteina)
