Orka is a fictional character appearing in American comic book published by Marvel Comics. The character was created by Roy Thomas and Marie Severin, and has a killer whale theme. Orka primarily appears as a villain fighting the Avengers, the Fantastic Four, She-Hulk, and the Defenders, and also appears as a member of Heroes for Hire.

Orka first appears in Prince Namor, the Sub-Mariner #23 (March 1970) and was created by Roy Thomas and Marie Severin.

Orka was originally an Atlantean soldier in the army of Warlord Krang, and aids the renegade Krang when he attempts to usurp the Atlantean throne from Namor. When this attempt fails, Orka goes into exile from Atlantis with Krang. Orka is then chosen to be the test subject of Dr. Dorcas, the marine scientist who created Tiger Shark, one of Namor's arch foes. Courtesy of a belt with a psionic amplifier, Orka is given the power of a killer whale, and aids Krang once more against Namor. The character skirmishes with fellow creation Tiger Shark, and the pair cause an undersea avalanche that buries them for several months.

Orka eventually freed himself and allies with the other-dimensional Virago, and after battling Namor twice is defeated. The Brand Corporation (a subsidiary of Roxxon Energy Corporation) summon Orka with the aid of the Serpent Crown, and in exchange for his aid is augmented: the character's size is increased to tall and his natural abilities are increased, eliminating the need for the psionic belt. Orka is sent on a mission that brings him into conflict with superhero team the Avengers, with Thunder God Thor knocking him unconscious.

Orka has not been a contender in any CBUB matches.
