House Ordos is an insidious, mercantile House in the Dune universe as presented in the Westwood Studios games. This House only appeared in the Dune Encyclopedia and is never mentioned in the actual novels.

In the Dune games series the Ordos house plays the most greedy and selfish house in the Dune universe, their only purpose is to harvest as much spice as they can and to destroy anything that stands between theme and the most valuable source in the entire universe. Their origins are narrated in the game as being an establishment of several wealthy families or 'cartels' who hired expensive but disloyal mercenaries to fight for the House. Their Mentats have often been reported to silently disappear under mysterious circumstances although the player can guess as to their possible fate. The House faces stiff competition for the spice in Arrakis but can still pose a threat.
