"It is a vast criminal syndicate, it's influence felt on every planet from the Core Worlds to the Outer Rim. Black Sun has existed for hundreds of years, and embedded itself in the very fiber of the galaxy. The resources at its disposal are almost limitless. The soldiers under its command number in the tens of thousands. The ignorant even call it the most powerful force in the known universe."
―Dantius Palpatine[src]

Black Sun was one of the most powerful and infamous crime syndicates in The Galaxy during the the last centuries of the Galactic Republic, the time of the Galactic Empire and the early years of the New Republic.
