Trantor is a fictional planet in Isaac Asimov's Foundation Series and Empire series of science fiction novels.

Trantor was first mentioned in Asimov's short story, "Black Friar of the Flame", later collected in The Early Asimov, Volume 1. It was described as a human-settled planet in the part of the galaxy not ruled by an intelligent reptilian race (later defeated). Later, Trantor gained prominence when the 1940s Foundation series first appeared in print (in the form of short stories). Asimov described Trantor as being in the centre of the galaxy. In later stories he acknowledged the growth in astronomical knowledge by retconning its position to be as close to the galactic centre as was compatible with human habitability. The first time it was acknowledged in novel form was in Pebble in the Sky.

The earlier history of Trantor is recapitulated in The Currents of Space, mentioning the five worlds of the Trantorian Republic growing into the Trantorian Confederation and then Trantorian Empire (evidently modeled on the Roman Republic, originally ruling only part of central Italy, developing into the vast Roman Empire).

At the time when Currents takes place, Trantor controls about half of the worlds in the Galaxy, while the other half is divided into innumerable independent worlds and miniature empires – which naturally makes a Trantorian Ambassador a person of great consequence on any of the still-independent worlds.

Later on, conquest of the entire galaxy made the Galactic Empire, with Trantor as its capital planet, a reality; the planet no longer sending out ambassadors, but only governors to royal subject worlds. This situation had already existed for thousands of years at the time of Pebble in the Sky, the next chronological book on this timeline.
