Sooncanoo Beacon was a Galactic Republic hyperspace beacon. It was situated in the Sooncanoo system, a part of the Northern Dependencies portion of the Inner Rim.
During the Waymancy Storm of 7811 BBY, the Fortieth Flotilla of the Republic underwent a risky attempt to boost the deflector shields of its starships at Sooncanoo Beacon. The attempt failed, leaving the flotilla to float powerless in space. Subsequently, one of the parties affiliated with the Republic's enemy in the war, the Signatories of Waymancy, massacred every crewmember of the Fortieth Flotilla. At a speech delivered on the 25th anniversary of Victory in the Waymancy Storm in 7786 BBY, the Republic's Supreme Chancellor Nagratha noted the massacre at Sooncanoo Beacon as one of the bloodiest events of the Waymancy Storm.
