The Ourg are an almost extinct race of gigantic ogre-like creatures, one of the most powerful races bred by the god Bandos. Ourgs had been thought to have died out over the course of numerous wars, until what is now known as the God Wars Dungeon thawed out and the last Ourg known to be alive thawed out with it. They were the race of General Graardor, the only one living to this day.

Players can also find Ourg Bones in Zogre coffins, after completion of Zogre Flesh Eaters.

It was discovered that Graardor belongs to the ourg race when Armies of Gielinor was released on FunOrb. In that game, the Ourg are one of Bandos's units (Graardor also being Bandos's general in the God Wars Dungeon). General Graardor also appears in the "Guthix Awakens" campaign, as do the previously unknown ourgs Blorgak and Yokrad.

In the quest The Chosen Commander , two Ourg statues can be found inside Bandos' throne room; one can be attacked after completion of the quest.

It has also been implied that Slash Bash from Zogre Flesh Eaters was an undead ourg.
