[[caption-width-right:232:You can run, but you can't hide... actually, [[TurnBasedTactics you can't run either.]]]]

A projectile or attack in interactive media (or a narrative description in non-interactive media) that homes in on its intended target. If you're firing it, it can be an effective means of eliminating targets without putting yourself in harm's way. If an enemy is firing it, you'll need to perform a HighSpeedMissileDodge, [[LuckilyMyShieldWillProtectMe whip out a shield]], [[MisguidedMissile trick its guidance system]], ShootTheBullet [[DestructibleProjectiles if it is destructible]], or [[MundaneSolution just outrun it until it loses steam]].

A curious trait of most homing attacks is their inability to [[LeadTheTarget "lead" a moving target]], resulting in them doggedly "trailing" behind if the target can move fast enough. Very few homing attacks will actually plot an intercept course on a moving target.

A fairly common projectile type in {{Shmups}} and TableTopGames.

Compare and Contrast with PlayerGuidedMissile

Subtropes include:
* ActionBomb in which the projectile in question doesn’t fly.
* BoomerangComeback in which the projectile starts homing after overtaking the target
** PrecisionGuidedBoomerang no matter what
* HomingBoulders in which the mechanic is there but doesn't make sense for the situation, such as boulders rolling at you that home in on your location.
* MacrossMissileMassacre in which a huge, ominous cloud of homing missiles is released.
* {{Roboteching}} in which the projectiles don't start homing until after they've flown a fair distance.
* PinballProjectile in which the projectiles move by bouncing off of non-targets.
** ReflectingLaser even if the projectile is a laser beam
*** HomingLaser especially lasers.
* SuperPersistentMissile in which the projectile not only guides itself toward a target but doesn’t give up if it misses.

[[folder:Anime and Manga]]
* ''Anime/WolfsRain'': the Noble's have access to laser weapons that home in on their targets, inexplicably.
* ''{{Hellsing}}'': Rip Van Winkle has a rifle that shoots magic bullets that can immediately home on a target or do very fancy {{Roboteching}}.
* ''DragonBallZ'': Goku (Kamehameha twin dragon shot), Krillin (Double Tsuihikidan), and Piccolo (Chasing Bullet) have all used homing Ki attacks at one time or another.
** Android 13's [[SphereOfDestruction S.S. Deadly Bomber]] took this even further, as the energy ball is seen making sharp ninty degree turns in its flight path to track its victim.
* Nami's Thunder Breed Tempo in ''OnePiece'' (a homing lightning bolt). In a CrowningMomentOfFunny, Franky also claims that his shoulder cannons do this, but subverts it when it's really just himself running after the opponent.
[[/folder]]

[[folder:Comicbooks]]
* ComicBook/{{Darkseid}} whose omega beams take great pains to hit their target.
[[/folder]]

[[folder:Film]]
* ''Film/{{Runaway}}'': A gun is introduced that fires projectiles that act like a tiny guided missiles.
* The same thing happens in ''Film/BabylonAD'', with the missile homing in on the nanite-passport injected in the protagonist's neck.
* ''Film/StarTrekVITheUndiscoveredCountry'': While most torpedoes are guided, and therefore should be guided InSpace, this movie had a particular torpedo that was explicitly seen to track a cloaked Klingon ship's ion trail.
[[/folder]]

[[folder:Live-Action TV]]
* ''Series/{{Andromeda}}'': The Force Lance from the series did a lot of things including launching homing projectiles.
* ''Series/MightyMorphinPowerRangers'': Kimberly's arrows possess this ability, as memorably demonstrated in "Power Ranger Punks".
* ''Series/AlmostHuman'': The episode "You are Here" featured a 50 caliber homing bullet fired out of a very nifty rifle, guided through a city by advertising software.
* An episode of ''Series/{{Flashpoint}}'' revolved around a thief aiming to steal a prototype smartgun, which (unrealistically) used radio waves to mark and track a target. This results in Ed Lane getting shot despite being behind cover. In the end, the SRU team uses a radio jammer to prevent the gun's bullets from tracking their targets, enabling them to take down the perp.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons'': Ranged weapons with the "seeking" enchantment.

[[/folder]]

[[folder:Videogames]]
* The Red Shells and Blue (aka. "Death-on-Swift-Wings-Comes-for-You") Shells in ''VideoGame/MarioKart''.

* Franchise/SonicTheHedgehog himself can become this through the Homing Attack. Other characters can do it as well, such as Shadow, Amy, and Espio.
* The upgraded single missile in ''VideoGame/DiddyKongRacing''.
* In ''VideoGame/ChimeraBeast'' your eater could evolve to have ExtraEyes on its body, which could then be fired out when you did your ChargedAttack. They homed in on enemies.
* ''VideoGame/{{Einhander}}'' had an ''awesome'' version of this- the Wasp missiles homed in on ''both background AND foreground targets'' as well!
* The homing laser beams and balls in ''VideoGame/{{Recca}}''.
* ''VideoGame/{{Tyrian}}'' has Heavy Guided Bombs and Guided Micro Bombs, the latter of which is dangerously close to a GameBreaker as it was akin to MacrossMissileMassacre.
* The chaser weapon in ''VideoGame/GunstarHeroes'' and ''VideoGame/AlienSoldier''.
* The homing missiles in ''VideoGame/{{Bangai-O}} Spirits''.
* The H weapon in ''VideoGame/{{Contra}} III'' and subsequent ''Contra'' games.

* Two of the weapons in ''VideoGame/RadiantSilvergun'' shoot homing projectiles.
* Anti-Aircraft missiles are one of the more useful subweapons in ''Tetrastar''.
* Pretty much all of the ''VideoGame/{{Touhou}}'' games have this as an available shot-type, usually held by Reimu. They also occasionally have homing projectiles as enemies' attacks -- most often in the form of bullets that periodically reorient themselves, but there are also projectiles with true homing, like Seiga's ball lightning.
* ''VideoGame/BubbleTanks 2 and 3'' have seeker missile [[SecondaryFire sub-weapons]], which do a good amount of damage.

* [[AIIsACrapshoot Sektor]] of ''Franchise/MortalKombat'' fame shoots homing missiles as a special move in ''VideoGame/MortalKombat3'' and ''VideoGame/MortalKombat9'', although in the latter it uses up a third of the Super Meter.
* Amazons in ''VideoGame/DiabloII'' can fire homing arrows. An early bug combined this with the Piercing skill to make the arrows home onto an enemy, hit them, pass through them, then turn around and do it again.
** Demon Hunters in ''VideoGame/DiabloIII'' can do the same. Overlaps with PinballProjectile when done in narrow passages, as it will look like the arrow bounces off the walls. In open spaces, however, the Demon Hunter can fire an arrow in the complete opposite direction of an enemy and the arrow will simply make a sharp turn mid-air and hit the enemy anyhow. Furthermore, the Demon Hunter has various skills that can also be upgraded with runes to fire homing rockets.
* Throughout ''Franchise/{{Halo}}'': [[AbnormalAmmo Needler]], Plasma Pistol.
** ''VideoGame/{{Halo 2}}'' Rocket Launcher.
** ''VideoGame/{{Halo 3}}'' Banshee Bomb, Missile Pod.

** HaloReach with the advent of armor lock, this is suddenly played for keeps: Rocket Launcher (AA only), Banshee Bomb, Rocket Hog turret, Plasma Launcher.
* ''Videogame/GunsOfIcarus'' includes homing rocket turrets.
* ''VideoGame/AceCombat'' has a variety of missiles for the player, ranging from the standard generic Missiles that can target anything and come in large numbers to more specialized long-range missiles that may do extra damage or lock on to multiple targets. Enemy pilots, especially ace pilots, can evade shots that aren't lined up properly.
** Enemy aircraft, ships, and SAM units can launch missiles at the player. Their homing capabilities are about equal to the player's standard missiles.
* The Bullet Bills in various 3D ''Franchise/{{Mario}}'' games home in on Mario to varying degrees.
** As well as the Missile Bills in the 2D games.
** In ''VideoGame/NewSuperMarioBrosWii'', Ludwig Van Koopa can shoot homing fireballs (thankfully much slower than regular fireballs).
* ''VideoGame/DonkeyKongCountry 3'': Barbos's shellfish flunkies home in on Enguarde, and and must be [[MisguidedMissile manipulated]] to knock out his barriers.
* One of Gruntilda's spells in ''BanjoKazooie'' can't be avoided without using [[InvincibilityPowerUp invincibility]].
* ''VideoGame/DonkeyKong64'': A big beeping missile with a face (of course) is used by the upgraded Army Dillo.
* The boss of stage 5 of ''VideoGame/MrGimmick'' shoots slow homing missiles that block your attacks.
* A fairly annoying attack by bosses in ''VideoGame/{{Darius}}'' games.
* Many enemies, minibosses and bosses in ''VideoGame/MegaMan'' franchise fire homing projectiles.
* ''VideoGame/SeriousSam I'' has reptiloids and final boss of ''The First Encounter'' shooting these. In ''SeriousSam II'' the enemies shooting homing missiles include witches, helicopters and two types of sci-fi orcs.
* In the similar ''VideoGame/WillRock'', two bosses (Hephaestus and Medusa) uses this.
* The revenants in ''VideoGame/{{Doom}}'' launch missiles that the player has to get real creative to avoid.
* Hellfire missiles fired by AI AH-64 helicopters will both lead and home onto Alex in ''VideoGame/{{Prototype}}''. But Alex cannot do the same when he's in an AH-64, meaning TheComputerIsACheatingBastard.
* Nearly all secondary weapons in ''VideoGame/FreeSpace'' - and some ''do'' LeadTheTarget.
* Several of Shepard's powers in ''VideoGame/MassEffect2'' and ''VideoGame/MassEffect3'' fire projectiles that home in on the target, allowing the powers to be fired in an arc around obstacles. Almost all of these powers when used by Shepard's squadmates instantly hit the target instead.
* ''Videogame/TeamFortress2'': Custom game mode "Dodgeball" has rockets which, unlike normal ones fired by the Soldier, home in on a player. The game is to use the Pyro's [[AttackReflector compression blast]] to deflect the rocket at the enemy team, who are trying to do the same.
* If you get your Dark-Elf's Disease Bolt spell high enough in ''Videogame/ChampionsOfNorrath'', it will home in and hit the nearest enemy.
* ''Videogame/DarkSouls'': Projectile sorceries usually home on the locked enemy.
** And in this game, even arrows veer mid-flight to better hit you.
* [[{{BFG}} Gun-type God Arcs]] in ''VideoGame/GodsEaterBurst'' can be loaded with homing bullets and ''lasers''. Saves some frustration when you're trying to hit something fast-moving, but homing attacks target center of mass and so [[AttackItsWeakPoint can't be used to aim at specific points on the Aragami]].
* Achieved accidentally as an artifact of the rendering engine in ''CityOfHeroes''. Most single-target attacks have a visible effect that take a short time to reach their target, so if an attack that has been determined to be a hit goes off against a moving target, the visible effect (fire beam, energy blast, etc.) will arc to follow the target, no matter how fast it moves or how many turns it makes. It is sometimes possible, with a travel power at the speed cap or with Teleportation, depending on where you start, to reach a street exit to another zone and exit the zone before the visible blast hits you, although you will still take the damage from the attack.
* ''VideoGame/RaptorCallOfTheShadows'' has orange flak balls that are shot at your plane instead of the normal ones that are shot straight. A large majority of Mooks, airborne and grounded, use these on you, especially on the later levels and harder difficulties; these make them GoddamnedBats.
* The best weapon pickup of ''VideoGame/PrehistorikMan'' was an egg that allowed the player to fire homing (and very damaging) dinosaurs at enemies.

[[folder:Western Animation]]
* ''WesternAnimation/{{Ben 10}}'': The series and the movie ''Destroy All Aliens'' has both homing and non-homing projectiles.
[[/folder]]

[[folder:Real Life]]
* [[http://www.popsci.com/technology/article/2012-05/rough-sketch-self-guided-bullet A group of engineers at Sandia National Laboratories are working on developing a homing .50 sniper's bullet.]] They started by removing the rifling from the barrel and adding movable stabilizer fins to the round. Electronics inside the bullet allow it to home on its target, to a point (it obviously won't be able to turn back around if you miss).
* In the meantime, the Italian and French navies already field it in their artillery: as their CISW doctrine calls for larger and longer-ranged guns in place of faster-firing but shorter-ranged weapons, the Italian firm OTO Melara (through his Otobreda branch) developed guided shells for their 76mm [[MoreDakka Super]] [[ExactlyWhatItSaysOnTheTin Rapid]] multi-purpose guns used by both navies, and, as the Italian Navy wanted more, [[UpToEleven developed a 127mm-caliber version and the new 127/64 Lightweight gun to fire it]].
** And to continue the long Italian tradition of CombatPragmatism in an era where some of the earlier tricks are done by everyone or would be war crimes, Iveco (maker of the Centauro tank destroyer) and OTO Melara gave us the [[http://www.military-today.com/artillery/porcupine.htm Porcupine]]: a prototype consisting of a Centauro chassis mated with a 155/39mm howitzer capable of firing homing shells to targets up to 60 km away. And the ability to hit the poor target with four of them ''at the same time''. Let's face it, when the Italians go at war they're assholes.
