Teplan I was an inhabited class M world, a planet in the space claimed by the Dominion. It was the first and only planet of the Teplan system, located in the Kendari sector of the galaxy's Gamma Quadrant. Teplan I was the homeworld of the Teplan people.

In the 22nd century, the space-faring Teplans resisted coercion by the Dominion. In return, the Jem'Hadar released the Teplan blight, a fatal disease, on Teplan I. Forced to focus on survival, the Teplan culture crumbled.
