Planet Quorg is a planet in the Spaceman Spiff universe. It appeared in a single Sunday strip.
Its geography was distinctly rocky; Spiff described the planet as "a desolate world of deep gorges and canyons".
No life-forms were seen on the planet, however, Spiff came across a trail of gigantic humanoid footprints, surprisingly almost identical to the imprint of a shoe. The spacefarer surmised that an alien had been looking for him in order to eat him, and Spiff took evasive action.
