Happy Birthday. What a wonderful day this is! You're a year older, so let's celebrate! Now, I know [[ItWasAGift the mystic artifact I got you]] [[TheLittleShopThatWasntThereYesterday from that guy who set up a booth on the street corner]] seems useless and thoughtless, but [[TheCallTwinksYou something told me it would be good for you]]. Yeah, see it [[PowerGlows glowing.]] It does that sometimes. Keep it in mind when you're fighting the DarkLord. If you're lucky, it will actually be important to the plot.

Now, Chekhov's Gift is not given an important purpose at first. It gains that with time. Now, that old hermit might give a gift that he knows will be useful, but you do not know immediately how important it is to the plot. The other case is that it was important by freak chance. It can be given for a Birthday, Christmas, or some other reason. The key factor is that it's not what it appears to be at first. SubTrope of ItWasAGift. See also ItMayHelpYouOnYourQuest. Compare MementoMacguffin.

Enjoy your sacred artifact. Hope you manage to SaveTheWorld.

!!Examples:

[[folder:{{Anime}} and {{Manga}}]]
* In ''Manga/{{Bleach}}'', Ichigo is given a''"Substitute Shinigami Combat Pass"'' that was supposed to identify himself to other resident Shinigami, but on first sight, it's apparently useless. [[TricksterMentor Urahara Kisuke]] later modifies it to shunt Ichigo to and from his human shell into his spirit form. [[spoiler: In truth, the badge was an instrument to suppress Ichigo's spiritual pressure and to keep tabs on him in case he betrayed [[SpiritWorld Soul Society.]]]]
* In ''Manga/{{Naruto}}'''s ''Kakashi Gaiden'', Minato's gift to Kakashi seemed like an ordinary if oddly-shaped kunai, but it was actually meant to summon Minato to Kakashi's location once it was thrown.
* In ''PokemonSpecial'', Blue gave Yellow a straw hat for disguise and gender-concealing reasons. It ultimately doesn't seem like it does much other than creating awkward tension between her and Red later, but it is eventually revealed that the two feathers that adorn the hat are really [[spoiler: the Rainbow and Silver Wings]].
* The heroine of ''Manga/NurseAngelRirikaSOS'' gets her TransformationTrinket as a birthday present.
[[/folder]]

[[folder:{{Film}}]]
* At the end of ''Film/StarTrekIITheWrathOfKhan'', Kirk realized that the birthday present Spock gave had a secret message hidden in it.
** Though, to Kirk's credit, he did suspect something when Spock gave the gift.
* In ''Film/ClashOfTheTitans'', Zeus gives three gifts to Perseus: a sword, a shield and a helm of invisibility. Later, Athena gives him Bubo the owl. All of them are useful to Perseus in his adventures, one way or another.
* Name a ''Film/JamesBond'' film! Bond always receives plenty of presents from Q. Some of the presents are made specifically for Bond's mission, but most really aren't. Coincidentally, and conveniently, every function of every item from Q just happens to be useful once (and only once) on Bond's mission.
** Most specifically, ''Film/LicenceToKill'', [[spoiler: in which Della and Felix Leiter give Bond a cigarette lighter as a wedding present. It is later used to light an petrol/cocaine soaked Franz Sanchez on fire, sending him to his doom.]]
** There is one exception - the exploding alarm clock from ''License to Kill'' ("Guaranteed to not wake up anyone who uses it") was never actually used.
* The British Horror Film ''Film/DogSoldiers'' features this with the silver item that a man gave to his girlfriend before their deaths.
* This is actually subverted in the first ''Franchise/StarWars: Film/ANewHope'' film; at the beginning it makes a fairly big deal about Luke being given his father's lightsaber by TheObiWan, but Luke never ends up actually using it for anything useful, and in the end saves the day with the piloting skills he picked up as a farmboy.
** Of course it ''does'' prove handy in the second film, saving Luke's life on Hoth.
* In the remake of ''Film/InvadersFromMars'', the mint condition vintage penny that David's father gives him is later used to power one of the Martians' weapons, which run off of copper.
* In ''WesternAnimation/MrPeabodyAndSherman'', when Sherman starts his first day of school, Peabody presents him with a dog whistle. Later Sherman blows the whistle when he's about to be cut down by a Trojan warrior. Peabody hears the whistle and saves him.
* In ''[[Film/SherlockHolmes Sherlock Holmes: A Game of Shadows]]'' Holmes gives Watson a gift of an adrenaline injection, after demonstrating its use by reviving a [[RunningGag dead Gladstone]]. Later when it looks like Holmes died of his injuries, Watson gives him the shot, reviving him and waking him from an apparently nightmarish fever dream involving a pony.

[[folder:{{Literature}}]]
* Literature/HarryPotter gets a lot of these: his invisibility cloak, a flute, his firebolt, and everything Dumbledore [[spoiler:left Harry in his will]].
** Everything Dumbledore [[spoiler:left Ron and Hermione in his will]] as well.
** Hermione's cat, Crookshanks, was an early birthday present that was crucial to the plot of the third book.
** Zigzagging with Sirius' magic knife. After he received it, he forgot it and just remembered that it would have been useful while in the second task of the Triwizard Tournament. In the next book he uses it once to break into Umbridge's office. Later, he remembers to take the knife with him to the ministry, but then it's melted and rendered unusable when he tries to open a locked door.
** Sirius' magic mirrors. Instead of using them, Harry uses the fireplace to communicate with him and [[spoiler:gets himself caught by Umbridge, as well as getting fooled by Kreacher, resulting in Sirius' death]]. Harry only remembers about them later and makes an attempt to communicate with Sirius [[spoiler:after he's already dead]], which obviously doesn't work. The mirrors are brought back into play in the seventh book when [[spoiler:Aberforth Dumbledore]] is using the other one to keep track of Harry.
* Father Christmas' gifts to the Pevensees in ''[[TheChroniclesOfNarnia The Lion, the Witch and the Wardrobe]]''.
* ''Literature/TheLordOfTheRings'' contains several examples:
** The One Ring itself. Which is actually rarely given as a gift, due to fact that anyone who possesses it finds themselves unable to give it up. However, Gollum repeatedly refers to the Ring as his "birthday present" in ''Literature/TheHobbit'', in order to disguise the fact that [[spoiler:he killed his own cousin, Déagol, to obtain the Ring.]] This happens to have occurred on Gollum's birthday.
** The ''mithril'' mail shirt that Bilbo gives Frodo saves his life in the Mines of Moria. This could also be seen as an extension of ''Literature/TheHobbit'' as well, since it is Thorin's gift to Bilbo that ultimately saves the hobbit's heir and assists in the Ring's destruction.
** Many of the gifts that Galadriel gives the Fellowship:
*** The phial containing the light of Eärendil that she gives to Frodo.
*** The box of dirt that she gives to Sam, which allows him to [[spoiler: rebuild the Shire after everything that Saruman does to it]].
*** The belt that she gives to Boromir [[spoiler: is what allows Frodo to confirm that Boromir is in fact dead and that Faramir's vision of finding Boromir's body wasn't just a dream]].
*** The "Elfstone" that she gives Aragorn becomes the symbol of his house and is the name he uses when he takes the throne.
*** The cloaks given to all members of the Fellowship hide them from enemies on numerous occasions.
* ''[[Literature/{{Chalion}} The Curse of Chalion]]'': [[AristocratsAreEvil Lord Dondo]] gives [[EverythingsBetterWithPrincesses Royesse Iselle]] a strand of pearls twice as long as she is tall. Much later, they are instrumental in saving the life of her betrothed.
* In ''[[ASongofIceandFire A Game of Thrones]]'', Daenerys gets a set of three stone dragon eggs as a gift for her marriage to Khal Drogo. [[spoiler:Turns out at the end of the book that they're not just rocks after all.]]
* In ''Literature/TheDresdenFiles'' Bianca gives Lea (Harry's very scary, very powerful and not entirely sane to begin with) [[TheFairFolk faerie]] godmother an athame which is said to be in the same power league as Amoracchius, which is implied to be the most powerful/untinkered with, of the Swords of the Cross. The next book, Lea passes on Harry's debt to her to Mab so she can keep the blade, which drives her batshit insane. Then Mab, Queen of the Winter Sidhe and on a par with gods and lower Archangels, gets hold of it. Cue massive OhCrap moment.
* In ''{{Literature/Cerberon}}'', Aladavan, a sidhe wizard, gives Robert a special sword called ''Magister'', which later becomes important in Darkram's SecretTestOfCharacter. It may have other significance that isn't revealed in the rest of the novel. (Maybe the next one?)
* ''Literature/TheInfernalDevices'':
** The [[spoiler: tiny clockwork angel sure comes in handy]]
** Also [[spoiler: Tessa's dislike for chocolate, and the gift Nate gives Aunt Harriet...]]
* In ''Literature/TheManWithTheRedTattoo'', Literature/JamesBond is given an antique Japanese sword as a gift for saving the day at the G8 summit. Not even a day manages to pass before he has to use it in a SwordFight against the BigBad trying to take revenge on him.

[[folder:LiveActionTV]]
* In ''{{Monk}}'', Trudy gives Monk a Christmas present just before she dies which is mentioned in the first and third [[ChristmasEpisode Christmas episodes]] of the show. Monk has refused to open it for 12 years. When he finally does open it, it's a [[spoiler:videotape of herself telling Monk who her killer might be]].
* ''Series/OnceUponATime'': [[Literature/RedRidingHood Red]] has the iconic red cloak that her grandmother gave her, insisting that the color red wards off [[TheBigBadWolf wolves]]. Red, who obviously doubts her grandmother's claims, often doesn't wear the cloak even during "wolfstime." It turns out that [[spoiler: the cloak ''[[HalfTruth does]]'' keep away the wolf... because it's an enchanted object that [[OurWerewolvesAreDifferent keeps Red from turning]]]].

[[folder:{{Theatre}}]]
* In ''Theatre/TheNutcracker'' ballet, Clara is given the nutcracker doll, which comes to life later on to help fight off the evil Mouse King.
[[/folder]]

[[folder:VideoGames]]
* A less superpowered example is the voice-recording pendant that [[KanaLittleSister Kana: Little Sister]]'s heroine receives from her brother in the opening scene of the game. [[spoiler:She uses it to record her final message to him, which he listens to in the end after Kana has died of organ failure]].
* In the retro point-and-click adventure "simon the sorcerer" on Simon's birthday a Dog arrived at his house carrying a Book adorned with unreadable symbols (It later turns out to have been calypso who was giving these to simon so he could rescue him). He shoved the book in the attic, thinking it worthless, and adopts the dog as a family pet. Later on the dog goes into the attic grabs the book and gives it to simon, who to his astonishment, can now read the book, but still thinks it's garbage and throws it over his shoulder. This triggers a portal to open to the magic kingdom where his adventure begins. Most of this occurs in the back-story (which is in the manual) and doesn't appear in the game
* In ''VideoGame/{{Mother 3}}'' [[spoiler:the Courage Badge Flint gives to Lucas (through Nippolyte) turns out to be a Franklin Badge.]]
* In the VisualNovel ''KatawaShoujo'' Hisao goes into an Antiques store in order by a present for Hanako's birthday in Lilly's route. While he is there, he notices a music box and decides that Lilly would like it and purchases it as a gift for her as well. [[spoiler:In her Good Ending she plays it for him in his hospital room to let him know that she didn't get on the plane and is staying in Japan with him.]]
* Midway through CastlevaniaDawnOfSorrow, Soma gets a talisman from Mina. It's a useless accessory, but [[spoiler:you need to equip it to avoid getting the Bad Ending]].
* ''{{Ib}}'': Ib's handkerchief, a gift from her mother for her ninth birthday. It gets a small mention at the start of the game, and is ever-present in your inventory. It's also the key to getting the best ending; [[spoiler:Ib lending it to Garry triggers his memories once they leave the painted world]].
* A very easy one to overlook is in ''VideoGame/MassEffect2''. When you first meet Mordin, he gives Shepard a Carnifex pistol. In ''VideoGame/MassEffect3'', if the player decides to prevent Mordin from releasing the cure for the genophage, regardless of what weapon Shepard is holding at the time, s/he will [[spoiler: shoot Mordin in the back with a Carnifex pistol.]]
[[/folder]]

[[folder:WebComic]]
* In ''Webcomic/{{Homestuck}}'', John receives birthday presents from his friends. Because of {{Stable Time Loop}}s, the presents turn out to all be [[spoiler: the authentic stuffed bunny from ''Film/ConAir'', at different points throughout its history. The final version of the bunny ends up saving John's life when he is cornered by the BigBad.]]
[[/folder]]

[[folder:WebOriginal]]
* Literature/WhateleyUniverse example: in one Chaka story, Chaka's ring gets coated with mithril (there's a mithril-secreting mutant at Whateley too) so she can't wear the ring. The mutant gives her a mithril bracelet, and Chaka gives the ring to Generator as a gift, in part because Generator is the only one small enough to wear the ring now. Both of these Chekhov's Gifts turn out to be lifesavers in later stories.
[[/folder]]

[[folder:WesternAnimation]]
* A {{subverted}} one from ''WesternAnimation/WinxClub'' S4: [[spoiler:The Winx receive the gift of life from the ethereal fairies in ep 23. Just the thing for saving Nabu when he's fatally injured during the Black Circle's betrayal of the earth fairies in the next episode...that is, until the Black Circle also take that away from them.]]
* In "[[Recap/MyLittlePonyFriendshipIsMagicS2E10SecretOfMyExcess Secret of My Excess]]" in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', the fire ruby Spike gives to Rarity.
* In an episode of ''WesternAnimation/TheSimpsons'', Bart gives Lisa a laser pointer as a birthday present. Later, Lisa uses that laser to blind the villain who is trying to kill Homer.
* In an ''WesternAnimation/{{Ewoks}}'' episode titled ''The Curse of the Jindas'', Wicket gives a rock on a necklace to Kneesaa. Everybody else laughs at it, but the rock is actually [[spoiler: Stone Wizard's long-lost tooth which will free the Jindas from their curse]].
