Good Guys Wear Black is a 1978 American martial arts action film starring Chuck Norris and directed by Ted Post. This was the second film to feature Norris as the star, following Breaker! Breaker! (1977). However, this is the one that Norris considers his "breakthrough".

Following years of kung fu film imports from Hong Kong action cinema during the 1970s, most notably Bruce Lee films followed by Bruceploitation flicks, Good Guys Wear Black launched Chuck Norris as the first successful homegrown American martial arts star, having previously been best known for his film debut as a villain in Bruce Lee's Way of the Dragon (1972). Good Guys Wear Black distinguished itself from earlier martial arts films with its distinctly American setting, characters, themes, and politics, a formula which Norris continued with the similarly successful Force of One (1979). The film featured a first screen appearance by Norris' brother Aaron Norris and the final appearance of Lloyd Haynes.
