The Deep Six are a fictional team of half-humanoid comic book villains created by Jack Kirby as part of the Jack Kirby's Fourth World set of DC Comics titles. They first appeared in The New Gods #2 (April-May 1971).

At the bidding of their master, Darkseid, the Deep Six exist for the sole purposes of combat and terrorism in his name. All six fish-like members possess superhuman strength as well as the ability to breathe and function underwater. In New Gods #5, Orion kills all of the Deep Six during a battle on Earth. A member named Slig returns only to be killed by Orion again.

The team returns to face Aquaman and his allies Koryak and Dolphin in Aquaman vol. 5 #6 (April 1995), where it is revealed that the team has been resurrected several times over the years, whenever Darkseid has use for them. The new members are actually "spawns" of the original, raised in birthing chambers. As the spawns were raised on Earth, they are more attuned to its ocean environments. All members of the Deep Six are believed to have slain one of Aquaman's past loves and mother of his child Koryak. In the ensuing battle, all six are seemingly slain themselves. This revived version of Deep Six later faces the Supermen of America in Supermen of America #2 (April 2000).

The Deep Six appeared as members of Alexander Luthor, Jr.'s Secret Society of Super Villains.

The Deep Six has not been a contender in any CBUB matches.
