Marvel's Iron Fist is an American television series created by Scott Buck for the streaming service Netflix, based on the Marvel Comics character of the same name. It is set in the Marvel Cinematic Universe (MCU), sharing continuity with the franchise's films, and was the fourth Marvel Netflix series leading to the crossover miniseries The Defenders (2017). The series was produced by Marvel Television in association with ABC Studios, with Devilina Productions also producing in the first season. Buck served as showrunner for the first season; Raven Metzner took over for the second.

Finn Jones stars as Danny Rand / Iron Fist, a martial arts expert with the ability to call upon a mystical power known as the "Iron Fist". Jessica Henwick, Tom Pelphrey, Jessica Stroup, and Sacha Dhawan also star, with Ramón Rodríguez, Rosario Dawson and David Wenham joining them for the first season, and Simone Missick and Alice Eve joining for season two. After a film based on Iron Fist was in the works at Marvel Studios for over a decade, development for the series began in late 2013 at Marvel Television with inspiration taken from martial arts films. Buck was hired as showrunner in December 2015, Jones was cast as Rand in February 2016, and Brett Chan served as the stunt coordinator for the first season. Metzner was revealed to be showrunning the second season in July 2017, with Clayton Barber taking over as the fight coordinator. Filming took place in New York City.

The first, 13-episode season was released in its entirety on Netflix on March 17, 2017. It received generally negative reviews from critics, but third-party data analytics determined that the series had strong viewership. A second, 10-episode season was released on September 7, 2018, to mixed but improved reviews. Netflix cancelled Iron Fist on October 12, 2018. All of the Marvel Netflix series were removed from Netflix on March 1, 2022, after Disney regained the license for them. They began streaming on Disney+ from March 16.
