In Isaac Asimov's Robot/Empire/Foundation series of novels, the Galactic Empire is an empire consisting of millions of planets settled by humans across the whole Milky Way Galaxy. Its symbol is the Spaceship and Sun logo.

Asimov created the fictional Galactic Empire in the early 1940s based upon the Roman Empire, as a proposal to John W. Campbell, after reading Edward Gibbon's The History of the Decline and Fall of the Roman Empire when he was working at the Philadelphia Navy Yard with Robert Heinlein. The concept evolved through short stories and novellas in Astounding Science Fiction magazine during the 1940s, culminating in the publication of the Foundation stories as a trilogy of books in the early 1950s.

As of 827 G.E. (Galactic Era, the number of years after its founding), the Galactic Empire comprises millions of inhabited worlds with 500 quadrillion residents. According to the Foundation series chronology established in the late 1990s, it comes into existence approximately 10,000 CE, year one of the Galactic Era. (The establishment of the Empire was originally 34,500 CE, according to Asimov's unofficial unpublished early 1950s chronology.) The Galactic Empire was made possible by the ability of humans to travel through hyperspace. The space navy of the Galactic Empire is called the "Imperial Navy". The empire's capital, named Trantor, is the closest habitable planet to the center of the galaxy, and the novels in the Foundation trilogy describe its fall, over a period of centuries, and a period of anarchy and decay, a parallel to the fall of the Western Roman Empire and the Dark Ages.
