Elak of Atlantis is a collection of sword and sorcery short stories by American author Henry Kuttner (1915–1958), gathering together all his tales featuring the title character.

[1] The book collects the author's four "Elak" stories, together with supplementary material that differs according to the edition.

All editions include a map of Kuttner's version of Atlantis deriving from an original by Jack Gaughan that first appeared in the anthology The Fantastic Swordsmen (1967).

The Paizo and Gateway/Orion editions dropped the Lovisi and Foster material in favor of an introductory essay by Joe R. Lansdale and supplemented the Elak stories with the two tales of Kuttner's other Sword and Sorcery hero, Prince Raynor.

The Diversion Books edition consisted of the four Elak stories alone, omitting all supplementary material except the map.
