Full Metal Panic! (フルメタル·パニック!, Furumetaru Panikku!?, often abbreviated to FMP!) is a series of light novels written by Shoji Gatoh and illustrated by Shiki Douji. The series follows Sousuke Sagara, a member of the covert anti-terrorist private military organization known as Mithril, tasked with protecting Kaname Chidori, a hot-headed Japanese high school girl.

Individual chapters are published on Monthly Dragon Magazine, followed by a paperback compilation released by Fujimi Shobo's Fujimi Fantasia Bunko. The novels are split between stories focusing on Sousuke's mission as a soldier of Mithril and comedic side stories centered on his life at Jindai High School.

The series has been adapted into different media; including three animated television series: Full Metal Panic! by Gonzo in 2002, Full Metal Panic? Fumoffu and Full Metal Panic! The Second Raid by Kyoto Animation in 2003 and 2005 respectively. An OVA was also released in 2006; and five different manga series.

Tokyopop licensed the novels for English-language publication in North America and released parts of the series, while ADV Films licensed and dubbed the first season and the spin-off. The second season was licensed by Kadokawa Pictures USA with ADV Films producing the dub yet again. Mandalay Pictures acquired the film rights to the series in 2009.
