Terradonians are a humanoid species either native to or present within E-Space.

The Alzarians met by the Fourth Doctor and Romana lived around a crashed Terradonian ship and believed themselves to be descendants of the crew. It was later discovered that they were actually descendants of the local Marshmen, who had killed the Terradonians but evolved to a new form that was similar to them.
