"The Paradise Syndrome" is a third season episode of the American science fiction television series, Star Trek, and was broadcast October 4, 1968. It is episode #58, production #58, written by Margaret Armen and directed by Jud Taylor.

In this episode, an alien device on a primitive planet erases Captain Kirk's memory, and he begins a new life with the planet's indigenous people modeled on Native American Indians.

On stardate 4842.6, the Federation starship USS Enterprise arrives at an earthlike planet in anticipation of deflecting an asteroid headed for it. With some time to spare, Captain James T. Kirk, First Officer Spock and Chief Medical Officer Dr. McCoy transport to the surface for a brief survey. They find an obelisk with strange markings as well as a humanoid species whose customs seem to follow those of various North American Native tribes. Returning to the obelisk, Kirk starts to communicate with the Enterprise but his actions open a trap door within the obelisk which Kirk falls into. Spock and McCoy are unable to open the door, and are forced to return to the Enterprise to oversee the asteroid deflection.

Kirk awakens with amnesia, and finds his way out of the obelisk. Women from the native people witness his appearance and proclaim him as a god, and take him back to their village. Miramanee, the tribal priestess, attempts to sway the elders of the tribe of Kirk's divinity, but they demand he prove himself. At that moment, other villagers arrive with a boy that had drowned in a nearby lake. Salish, the medicine chief, declares the child dead, but Kirk uses mouth-to-mouth resuscitation to revive the boy. The elders accept Kirk as their god, forcing Salish to give up his position. Kirk, when asked his name, can only recall it as "Kirok".
