Spriggan (Japanese: スプリガン, Hepburn: Supurigan) (stylized in all caps) is a Japanese manga series written by Hiroshi Takashige and illustrated by Ryōji Minagawa. It was serialized in Shogakukan's shōnen manga magazines Weekly Shōnen Sunday and Shōnen Sunday Zōkan from 1989 to 1996, with its chapters collected in 11 tankōbon volumes. In North America, the manga was first licensed by Viz Media, under the title Striker; it was serialized in Manga Vizion and only three volumes were released in the late '90s. The manga was licensed by Seven Seas Entertainment, with its original title, in 2022.

Spriggan takes place in the last years of the Cold War where mysterious and unknown artifacts called out-of-place artifacts (OOPArt) are discovered in various parts of the world, leading to a secret war between various forces against the ARCAM Corporation, an organization that placed itself as the guardians of the OOPArts in order to prevent them from being used as weapons.

The manga was adapted into an anime film by Studio 4°C in 1998; Katsuhiro Otomo was involved in adapting. A PlayStation game called Spriggan: Lunar Verse was also based on the manga with some material created for the game. An original net animation (ONA) series adaptation by David Production was released in June 2022 on Netflix.

An ancient civilization known for their advanced technology once ruled Earth, but were destroyed in the end by their misuse. They left messages for later generations in the form of indestructible message plates written in ancient Hebrew, informing them that if they could not find a good use for their creations, they should be destroyed.

Various paramilitaries, national armies, and armed private forces began to secretly search for these "mysterious artifacts" in order to be used for their own good and against their enemies. The ARCAM Corporation and their military arm, the ARCAM Private Army, aim to stop these forces from destroying themselves with their elite secret agents known as Spriggans (or Strikers).
