Dragon Ball Z is a Japanese anime television series produced by Toei Animation. Part of the Dragon Ball media franchise, it is the sequel to the 1986 Dragon Ball television series and adapts the latter 325 chapters of the original Dragon Ball manga series created by Akira Toriyama. The series aired in Japan on Fuji TV from April 1989 to January 1996 and was later dubbed for broadcast in at least 81 countries worldwide.

Dragon Ball Z continues the adventures of Son Goku in his adult life as he and his companions defend the Earth against villains including aliens (Vegeta, Frieza), androids (Cell), and magical creatures (Majin Buu). At the same time, the story follows the life of Goku's son, Gohan, as well as the development of his rivals, Piccolo and Vegeta.

Due to the success of the series in the United States, the manga chapters making up its story were initially released by Viz Media under the Dragon Ball Z title. The anime's popularity has also spawned various media and merchandise that has come to represent the majority of the material within the Dragon Ball franchise, including films, home video releases, soundtracks, trading cards, and video games. Dragon Ball Z remains a cultural icon through numerous adaptations and re-releases, including a remastered broadcast titled Dragon Ball Z Kai.

Dragon Ball Z has since been followed by a sequel series titled Dragon Ball GT (1996–1997) and a "midquel" series titled Dragon Ball Super (2015–2018).
