Trigun

is a Japanese manga series written and illustrated by Yasuhiro Nightow. It was first serialized in Tokuma Shoten's manga magazine '''' from March 1995 to December 1996, until the magazine ceased its publication; its chapters were collected in three volumes. The series continued its publication in Shōnen Gahosha's manga magazine Young King OURs, under the title Trigun Maximum, from October 1997 to March 2007. Shōnen Gahosha republished the Trigun chapters in two volumes, and collected the Trigun Maximum chapters in 14 volumes.

Set on the fictional planet known as No Man's Land, the plot follows Vash the Stampede, a famous gunman who is constantly fighting bounty hunters seeking to obtain the immense bounty on his head. As the narrative progresses, Vash's past is explored. Trigun originated from Nightow's fascination with Western movies. Nightow wanted Vash to be different from cowboys in Western movies by avoiding killing enemies and instead exploring the characters involved in each story arc.
