Kenji Yamamoto (born July 1, 1958) is a television composer best known for his work on the Dragon Ball franchise. Yamamoto composed material for Dragon Ball Z, Dragon Ball Kai, and various tie-in games.

In 2011, after a year’s worth of speculation from fans, Toei Animation revealed that Yamamoto had a history of plagiarizing from other artists. Consequently, he was fired from the company, and the episodes of Dragon Ball Kai that he scored were edited to replace his music with pieces that Shunsuke Kikuchi wrote for the original Dragon Ball and Dragon Ball Z.

Yamamoto is not to be confused with Nintendo composer Kenji Yamamoto, born in 1964. The two artists' names are Romanized identically, but are written with slightly different kanji; the Nintendo composer’s name is written as 山本 健誌, while the Dragon Ball composer is 山本健司.
