0413 Theta was the designation for a Terran laborer aboard the space station Terok Nor. By 2370, he had been promoted to Theta after working in the mines as a lambda.

That year, he was caught by the station's security stowing aboard a freighter. Brought before Intendant Kira Nerys by Gul Elim Garak, she had him demoted back down to a lambda. With Kira's approval, Garak interrogated 0413 Theta on the identity of those who helped him get aboard the freighter. (DS9: "Crossover")

0413 Theta was played by Jack R. Orend.
