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 for anything further than point-blank range). Some can reel in anything the harpoon latches onto, thus working like a GrapplingHookPistol.

See JavelinThrower for the stone-age equivalent.



* In the ''Manga/BlackLagoon'' arc involving the neo-Nazis, Dutch gives Revy an underwater rifle, which amounts to a harpoon gun capable of full-auto.
* ''Manga/AttackOnTitan'' contains multibarreled versions [[spoiler: intended to capture the Female Titan]]

* In ''ComicBook/TheLeagueOfExtraordinaryGentlemen'', Captain Nemo has both a typical (but quite oversized) harpoon gun and a model of his own design that is more akin to a [[GatlingGood gatling gun]]. Designing weapons is a bit of a hobby for him.
* ComicBook/{{Aquaman}} foe Black Manta sometimes uses a wrist mounted harpoon gun. The harpoons are sometimes electrified too.

* The climactic battle in ''Film/{{Thunderball}}'' is fought by at least fifty men armed with harpoon guns. The use of a harpoon gun on a [[{{Mooks}} mook]] led to the immortal line, “I think he got the point”. [[spoiler: And the main villain is killed this way by his girlfriend.]]
** Also, Bond kills a mook with a harpoon gun in ''Film/LicenceToKill''.
--> Compliments of Sharkey!
* The final fight of ''Film/FaceOff'' involves a harpoon gun.
* ''Film/StarTrekIVTheVoyageHome'': at the end of the movie, some whalers shoot a Harpoon Gun at the rescued whales.
** Their expression is priceless when [[spoiler:it bounces off a cloaked [[CoolStarShip Bird-of-Prey]], which then proceeds to [[GunshipRescue decloak]]]].
* ''Film/JeepersCreepers2'': Jack Sr hunts the Creeper using a homemade harpoon gun.
* In ''Film/FridayThe13thPartIII'', Jason uses harpoon gun to kill Vera, namely shooting [[EyeScream her in the eye]].
** In [[Film/FridayThe13thTheFinalChapter the next film]] he uses a harpoon gun to kill one of the men. By stabbing him into the groin and finishing it by pulling the trigger.
** In ''[[Film/FridayThe13thPartVIIIJasonTakesManhattan Part VIII]]'', Jason uses one of these to kill a teenager on the boat - but since he doesn't have the coordination to pull back the bungees, the unlucky schlub gets stabbed with the ''whole'' harpoon gun.
* ''Film/TheDeadPool''. A deck harpoon gun is shown being fired for a horror movie. This is a ChekhovsGun for when Dirty Harry (presumably because his .44 Magnum is no longer the most powerful handgun in the world) dismounts it in the finale as a {{BFG}} against the killer.
* The BigBad is killed with a big one in
* The killer in ''Film/HappyHellNight'' gets harpooned when he is stalking the protagonists in the attic.
* Frequently used as weapons in ''Into The Blue''.
* ''Porno Holocaust'' ends with the mutant being anticlimactically killed by a shot to the chest with a speargun.

* ''Literature/ASeriesOfUnfortunateEvents'' involves a harpoon gun in the twelfth book, even lampshading its status as a ChekhovsGun. [[spoiler:Dewey Denouement is accidentally killed with it]]. [[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.]]
* Discworld book ''Discworld/TheFifthElephant'' features a small concealable weapon consisting of a tube, a spring and a crossbow bolt, which seems to be a sort of miniature harpoon gun.
* Divers in ''[[Literature/GreatShip The Memory of Sky]]'' is ([[HealingFactor temporarily]]) killed after an explosive-tipped harpoon is fired into its gut from an [[ZeppelinsFromAnotherWorld airship's]] [[StarfishAlien corona-killing]] harpoon cannon

* Used several times by Mike Nelson in ''SeaHunt,'' and in the similar shows ''The Aquanauts'' and ''Malibu Run.''
* In an episode of ''Series/GilligansIsland'', it's revealed that a man the passengers of the Minnow all had reason to hate was killed with one of these just before the boat left on its "three-hour tour." In the end, we learn that [[spoiler: the man was killed by accident, and not murdered.]]
* Used by Delano's {{mooks}} in the season 3 premiere of ''Series/HawaiiFive0''.

* The early harpoon gun (cannon actually) in ''TabletopGame/{{GURPS}}: High-Tech'' comes with two caplocks and a brass cover for them due to it being used on ships where the spray was likely to prevent the simple caplock mechanism from working.
* Creator/GamesWorkshop games:
** ''TabletopGame/DarkHeresy'' has the Impaler-an unreliable weapon constructed of scrap metal and used by hive gangers too poor to afford even a blackpowder weapon. Being little more than a rough metal tube and salvaged springs, these unwieldy weapons are nonetheless effective; launching meter-long spikes of sharpened metal at sufficient velocities to puncture carapace armor and pin bodies to plasteel walls.
** ''TabletopGame/{{Gorkamorka}}'' has two types of harpoon gun that can be mounted on vehicles, the rapid fire spear gun (consisting of racks of steam powered tubes stuffed with spears) and the powerful but short ranged harpoon gun. These weapons are cheaper and easier to maintain than more complex weapons and are therefore popular with inexperienced and down on their luck mobs.
** ''TabletopGame/{{Necromunda}}'':
*** During the 1st and 2nd Editions of the game, the [[LizardFolk Scales]] who accompanied Scavvy gangs could be armed with spear guns, massive and brutal weapons that fired a short-hafted spear with such force that it could [[OneHitPolykill pass straight through an enemy to impale another behind them]].
*** 3rd Edition Orlock gangs have access to harpoon launchers as a special weapon. The gangs use these weapons to impale their targets so that they can be [[MadeASlave captured alive to work in the mines and factories of the highly industrial House]].
* Unsurprisingly, ''[[TabletopGame/SeventhSea 7th Sea]]'' has harpoons, harpoons guns, [[GrapplingHookPistol grappling pistols]], and a Swordsman school or two based around using them.

* ''Toys/{{BIONICLE}}'': Vezok's Water Harpoon and Hahli Inika's Laser Harpoon

* Harpoon Guns are one of your starting weapons in ''VideoGame/XComTerrorFromTheDeep''. 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/HalfLife2'', 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/GodOfWarIII'' in a puzzle.
* ''VideoGame/TimeSplittersFuturePerfect'' 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.
* The old arcade title ''VideoGame/{{Pang}}'', aka ''Bros Buster Bros'', aka ''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.
* ''VideoGame/MassEffect3'' has the Harpoon Rifle Kishock, a multiplayer-only (though it can be added to single-player by buying a DLC) sniper rifle which fire harpoon. It's incredibly powerful and transform the [[LuckilyMyShieldWillProtectMe Cerberus Guardians]] into pushovers.
* One of many weapons that can be added to levels in ''VideoGame/HappyWheels''. Often you will have to dodge a [[RainOfArrows barrage of them]].
* In ''Videogame/{{Warframe}}'', the Grineer Harpak assault rifle fires fairly compact harpoons in a three-shot burst, with a SecondaryFire that launches a tethered harpoon that violently yanks back whatever it hits. The infested Paracyst 'rifle' is functionally identical.
* In ''VideoGame/{{Fallout 4}}'''s ''Far Harbor'' DLC, the Harpoon Gun is a ship-mounted harpoon gun what has been modified to be able to be carried by human hands. It can be modified to fire barded harpoons to apply bleeding effect or fire entire FlechetteStorm of harpoons.
* In ''VideoGame/{{Evolve}}'', the trapper character Griffin carries one of these that can link the monster to himself with an energy cable, allowing him to stop it in its tracks or restrict its movement until it breaks the cable. Maggie uses harpoon traps, a combination of his harpoon gun and land mines that can snare the monster from multiple angles at once.
* One of the aquatic weapons in ''VideoGame/GuildWars2'' is the harpoon gun, utilized differently by the four professions that can wield it.
* ''VideoGame/TreasurePlanetBattleAtProcyon'' has a Harpoon Gun as a light weapon, it enables the player to grapple enemy ships, which can be used for manipulating the movement of hostile ships and is a prerequisite to [[{{Boarding Party}} boarding]]. Grappling hooks can even tear ships apart if two ships grapple one and move in the opposite direction.
* ''{{VideoGame/Solatorobo}}'': The FishingMinigame involves firing a Mini-Mecha-mounted harpoon at a giant lobster-like FlyingSeafoodSpecial, who use derelict battleships as shells.

* 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}}'', [[spoiler:Surge's]] harpoon has this functionality. CC uses this as a grappling hook to help her navigate the goo-flooded basement.

[[folder:Web Original]]
* ''WebAnimation/DSBTInsaniT'': Lisa and Cody use them in the game they play in [='VRcade'=].

* In ''WesternAnimation/ActionLeagueNow'', team member Stinky Diver would often wield one of these; half the time, whatever problem the Action League was facing that week would be solved by Stinky simply harpooning it.
* In ''WesternAnimation/TuffPuppy'' in the episode "Mission: Really Big Mission" D.O.O.M. used these against Dudley and Kitty.
