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 Shikidouji. The series follows Sousuke Sagara, a member of the covert anti-terrorist mercenary group Mithril, tasked with protecting Kaname Chidori, a spirited Japanese high school girl.

Individual chapters are published on Monthly Dragon Magazine, followed by a paperback compilation released by Kadokawa Shoten'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.

Full Metal Panic! has been adapted to other media a number of times, including an animated television series by Gonzo in 2002.
