One-Punch Man (Japanese: ワンパンマン, Hepburn: Wanpanman) is a Japanese superhero franchise created by the artist ONE. It tells the story of Saitama, a superhero who can defeat any opponent with a single punch but seeks to find a worthy foe after growing bored by a lack of challenge due to his overwhelming strength. ONE wrote the original webcomic version in early 2009.

A digital manga remake began publication on Shueisha's Tonari no Young Jump website in June 2012. The manga is illustrated by Yusuke Murata, and its chapters are periodically compiled and published into individual tankōbon volumes. As of September 2020, 22 volumes have been released. An anime adaptation produced by Madhouse was broadcast in Japan from October to December 2015. A second season produced by J.C.Staff was broadcast from April to July 2019. In North America, Viz Media has licensed the remake manga for English serialization in its Weekly Shonen Jump digital magazine, and the anime adaptation, which premiered on Adult Swim's Toonami block in June 2016.

As of June 2012, the original webcomic surpassed 7.9 million hits. As of July 2019, the manga remake had over 20 million copies in circulation.
