The chapters of the Japanese manga Ichi the Killer are written and illustrated by Hideo Yamamoto. The series follows Ichi, a killer for a group of outcasts trying to survive in the yakuza world of the red-light district in Kabukichō, Tokyo. The manga was originally serialized in the Shogakukan magazine Weekly Young Sunday. Shogakukan has collected the chapters into ten volumes in Japan from 1998 to 2001. The volumes were republished in 2007.
Yamamoto has also written a predecessor titled Ichi in 1993. Ichi and an extra story titled The Birth were compiled together into Koroshiya Ichi Bangaihen on September 15, 2007.
In August 2024, Seven Seas Entertainment announced that it had licensed the series and will be released in a five-volume omnibus edition starting in July 2025, followed by the release of a "Volume 0".
