Chancellor Palpatine Spaceport
From Wookieepedia, the Star Wars wiki.
Chancellor Palpatine Spaceport was a facility built on Coruscant during the first ten years of Palpatine's chancellorship. When it was connected to the Chancellor Palpatine Commercial Nexus, it became Coruscant's primary spaceport, taking over that position from the older Galactic City Spaceport.
After the end of the Clone Wars, it was presumably renamed Emperor Palpatine Spaceport.
