Coruscant is a planet in the fictional Star Wars universe. It first appeared onscreen in the 1997 Special Edition of Star Wars Episode VI: Return of the Jedi, but was first mentioned in Timothy Zahn's 1991 novel Heir to the Empire. A city occupying an entire planet, it was renamed Imperial Center during the reign of the Galactic Empire (as depicted in the original films) and Yuuzhan'tar during the Yuuzhan Vong Invasion (as depicted in the New Jedi Order novel series). The adjective form of the planet name is Coruscanti.

Coruscant is, at various times, the capital of the Old Republic, the Galactic Empire, the New Republic, the Yuuzhan Vong Empire and the Galactic Alliance. Not only is Coruscant central to all these governing bodies, it is the navigational center of the galaxy, given that its hyperspace coordinates are (0,0,0). Due to its location and large population, the galaxy's main trade routes — Perlemian Trade Route, Hydian Way, Corellian Run and Corellian Trade Spine — go through Coruscant, making it the richest and most influential world in the Star Wars galaxy.
