A SubTrope of UnusualWeaponMounting and sister to the ArmCannon, the Leg Cannon is a cannon mounted on a leg, hidden in a leg, or IS the leg. Expect many of the same features as you would on an ArmCannon, such as BottomlessMagazines and being fired on [[UnusualUserInterface thought alone]], if only because you could not easily reach a trigger mounted on your own shins.

* Pictured above: ''{{Cyborg 009}}'', where Albert/Cyborg 004 has a rocket launcher installed in both of his legs. In a certain scene, he leaps in the air and [[CrowningMomentOfAwesome swiftly fires both rockets at the same time.]]
* ''Anime/TheBigO'': Big Duo has them.
* ''Anime/{{Daitarn3}}'' has the ''DAITARN LEG CANNON!''
* ''Manga/FullmetalAlchemist'': the pickpocket Paninya has rather unique automail legs, one of which is a 1.5" carbine housed in her left knee.
* ''GundamWing'': all incarnations of the Heavyarms Gundam have leg mounted missile launchers, among [[GatlingGood other]] [[ShoulderCannon things]].
* [[{{Gundam0083}} Post One-Year War variants]] of the Zaku II produced by the Zeon, and its successor, the Titans-produced [[ZetaGundam Hizack]], feature leg mounted missile launchers. Note that the Federation Zaku II's are not included, since most of them were Zeon Zakus captured during the end of said war and re-commissioned as Federation-use units
* In season 2 of ''{{Gundam 00}}'', the Seravee Gundam has beam cannons which fold out from its knees.
* In ''Anime/MobileSuitGundamAGE'', Gundam AGE-1 Spallow has needle guns which can be launched from its knees.
* ''Anime/MazingerZ'': [[{{Robeast}} Mechanical Beast]] Deviler-X1 had cannons mounted inside his legs. The Beast blew one entire Mazinger's arm off with one of them. Ouch.
* In one ''Manga/CityHunter'' arc, a bad guy who was humiliated by Ryo Saeba turns himself into a weapon, using an assault rifle for an arm and a GrenadeLauncher for a leg. Neither weapon does him much good against Saeba in the end, even dying ''because'' [[HoistByHisOwnPetard of his leg bazooka]], as Saeba [[ImprobableAimingSkills shot a bullet in the barrel]] as he was about to launch his grenade.
* The villainous Bonnie in ''GunsmithCats'' first encounter went badly for her: Rally shot her thumb off and one of May's grenades blew off her legs below the knee. When she returned for revenge her new prosthetic replacements included a [[ShotgunsAreJustBetter shotgun]] in one leg (with a bomb in that foot) and a thumb that included a garrot.
* ''OnePiece'' has Buggy the Clown, who somehow manages to hide a functioning gun in his foot with the proportional power of a giant cannonball that can be used to level cities. It's not clear whether it's actually in his foot or his shoe, however, but seeing as his super power is the ability to harmlessly separate individual parts of his body, there's a lot of wiggle room.
** Baby 5, who has the ability to turn her limbs or whole body into any weapon of her choice, has been seen transforming her leg into a machine gun.

[[folder: Tabletop Games ]]

* Occasionally, in ''TabletopGame/BattleTech'', some 'Mechs carry weapons in their legs. In spite of [[CaptainObvious the importance of their legs to the 'Mech's effectiveness]], the limited space and aiming restrictions for the leg locations means most 'Mechs don't mount weapons there, and heat sinks or jump jets are far more common alternatives. Notable examples of 'Mechs with leg weapons included the light Wasp and the heavy Crusader, both of which carry leg-mounted short range missile launchers. One particular piece of equipment called the A-Pod (antipersonnel-pod) is unusual in that its ''only'' allowed mounting points are in the legs. As it is essentially a leg-carried claymore mine, this is justified-- infantry making focused attacks on 'Mechs have to scale them first, and these mines easily shred conventional infantry.
