Berserk is a Japanese manga series written and drawn by Kentaro Miura, and has been published by Hakusensha in the magazines Monthly Animal House (1989–1992) and Young Animal (1992–). Since the late 2000s, the manga has been published irregularly, with frequent hiatuses until Miura's death in 2021. Since then, the series has been supervised by Miura's friend Kouji Mori and drawn by Studio Gaga, consisting of Miura's assistants and apprentices.

The story follows Guts, an orphaned mercenary on his quest for revenge, and consists of five major story arcs: "The Black Swordsman Arc" (volumes 1–3); "Golden Age Arc" (volumes 3–14); "Conviction Arc" (volumes 14–21); "Falcon of the Millennium Empire Arc" (volumes 22–35); and "Fantasia Arc" (volumes 35–).

The chapters (called "episodes") are since November 26, 1990, also collected by Hakusensha in tankōbon volumes; the posthumous 41st volume, which includes the final chapters that Miura had created for the series, was released in 2021. 42 have been released as of 2023. Dark Horse Comics has been releasing the English editions of the volumes since October 22, 2003, and began publishing hardcover editions containing multiple volumes on February 27, 2019. The Japanese volumes were re-released with new cover art starting in 2016, following the rebranding of Hakusensha's Jets Comics imprint as Young Animal Comics.
