The USS Defiant is the name of two starships in the Star Trek media franchise, most notably featured in the television series Star Trek: Deep Space Nine (1993–1999) and the film Star Trek: First Contact (1996). Introduced in Deep Space Nine's third season, it is a warship attached to the show's eponymous space station. The original Defiant is destroyed during the Dominion War in the seventh season and replaced with a largely identical ship.

The Defiant was designed by Jim Martin, Gary Hutzel and Tony Meinger.
