Sometimes, a bow and a quiver of arrows aren't big enough to finish the job; you'll need [[BladeOnAStick spear-sized]] arrows. Thankfully, there's the Harpoon Gun for that.

Harpoon guns are used by divers. In fact, any firearm designed for underwater use is basically a miniature harpoon gun (normal guns simply won't work). Some can reel in anything the harpoon latches onto, thus working like a GrapplingHookPistol.

See JavelinThrower for the stone-age equivalent.

[[DarkActionGirl Esme]] also whips one out in the seventh book, failing to [[spoiler:pop the balloons of Hector's flying house]] but succeeding at [[spoiler:destroying Duncan and Isadora's notebooks full of secrets.]] It's also a major point of suspense in the final book as to when the last spear will be fired, and it finally does, [[spoiler:mortally wounding Count Olaf.]]

[[folder: Video Games ]]

* Harpoon Guns are one of your starting weapons in ''[[VideoGame/{{X-COM}} X-COM: Terror of the Deep]]''. They quickly become obsolete.
* The harpoon gun in the first ''VideoGame/DevilMayCry''. Entering water with it caused an UnexpectedGenreChange to FPS since it was the only weapon you could use.
* ''VideoGame/BioShock2'': the Spear Gun, with uses normal spears, rocket spears, and trap spears.
* In ''VideoGame/{{Half-Life 2}}'', picking up a harpoon with the gravity gun automatically orients it in a "impale whatever I launch this at" position, making it into a makeshift harpoon gun (rather than the usual "large heavy objects" or sawblade gun).
** The harpoons seem to be surprisingly glitchy (it can kill friendly [=NPCs=], for instance). See [[http://www.halflife2.net/forums/showthread.php?t=127882 this forum thread]] (go to "Appendix 1") for details.
* More than one quest in ''[[VideoGame/WorldOfWarcraft World of Warcraft: Wrath of the Lich King]]'' involves shooting down proto-drakes with a harpoon gun. Most notable is the boss Skadi the Ruthless, who has to be shot down before your party can properly fight him on the ground.
* Your first ship in ''VideoGame/SkiesOfArcadia'' has one. Mind you, it's a ship-sized centerline-mounted harpoon ''cannon'' capable of impaling a battleship.
* Used in ''VideoGame/GodOfWar 3'' in a puzzle.
* ''VideoGame/TimeSplitters: Future Perfect'' has a harpoon gun with retrievable ammo.
* ''VideoGame/{{Crackdown}}'' had one as DLC. You could stick thugs to walls to use as stepping stones, or stick them to cars for an achievement.
* A few of the early ''Franchise/TombRaider'' games have this as one of the many weapons you can get. Naturally, this was the only weapon you could use while swimming in the water, but it was as weak as the default pistols.
* ''VideoGame/DeadSpace2'': the Javelin Gun, and its secondary fire electrocutes whatever was punctured by the javelin.
* Your main weapon in the NES ''VideoGame/{{Jaws}}'' game.
* Used by Dimitri Lousteau in his [[UnderTheSea underwater levels]] in ''VideoGame/Sly3HonorAmongThieves''.
* Bubble Man from ''VideoGame/RockmanNoConstancy'' uses a Harpoon ArmCannon.
* ''[[VideoGame/ArcanumOfSteamworksAndMagickObscura Arcanum]]'s'' insanely powerful, armor class ignoring Blade Launcher.
* ''VideoGame/{{Commandos}}: Behind Enemy Lines'' and ''Beyond the Call of Duty'' gives one to the Marine. It silently kills enemies at very short range.
** He can use it as well in ''Commandos 2''. The weapon can only be selected underwater but once it has been used underwater, the Marine can fire it on land using the Ctrl key.
* ''[[http://en.wikipedia.org/wiki/Buster_Bros Buster Bros.]]'', an old arcade game also known as ''Pang'' or ''Pomping World'', and its sequels features characters popping giant balloons with harpoon guns.
* The Helsing of ''VideoGame/{{Metro 2033}}'' and ''VideoGame/MetroLastLight'' is called a pneumatic crossbow, but in function it's more like one of these. It loads arrows in a pepperbox-like arrangement and uses pressurized air to launch highly lethal metal bolts. They are mostly silent and powerful enough to be a OneHitKill on human enemies, and have recoverable, reusable ammo. Its main downside is cost, with arrows being expensive to purchase or lose.

[[folder: Webcomics ]]

* In ''Webcomic/{{Homestuck}}'', Jade Harley owns one of these and uses it as a GrapplingHookPistol. Additionally, Eridan Ampora ([[spoiler:and later Liv Tyler]]) wields a legendary harpoon gun called Ahab's Crosshairs, which fires lightning.
* In ''WebComic/{{Waterworks}}'', the green gun CC uses to navigate the Goo.
