The Tevak shipyards were a Cardassian-Dominion shipyard.

In 2375, elements from the Cardassian Rebellion sabotaged the shipyard's dilithium storage bunkers, which vaporized the facility. The raid was made possible by Odo, who infiltrated the operations center and disabled the security protocols. (DS9: "Tacking Into the Wind")

According to Star Trek: Star Charts (p. 46) and Stellar Cartography: The Starfleet Reference Library ("Stellar Cartography", pp. 18-19; "Federation Historical Highlights, 2161-2385"), there was a star system named Tevak, which might possibly be the location of this shipyard, in the Alpha Quadrant. This was a trinary system with a M-class star, a K-class star, and an A-class star. According to a map of the Cardassian Union – prepared by an anonymous astrography clerk, from the Cardassian Central Archives, in 2364 – Tevak was identified as a Cardassian system.
