* In ''VideoGame/UndeadDarlings'', Pearl attempts this on Reggie in one subevent, but closes her eyes and accidently headbutts him too hard.

[[folder: Real Life]]
* Forehead Thermometers have gained popularity during the UsefulNotes/COVID19Pandemic because they are a no-contact means of taking someone's temperature. Not good for ShipTease though, as it just looks like you're about to zap them with a RayGun.

* Happens in ''Manga/HimeChanNoRibon'', when Himeko is caught hiding in her crush's room while disguised as said crush's little sister.

* Shows up in chapter 2 of the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic ''Fanfic/ADelicateBalance'', with Applejack doing it to Twilight.

* Haruka performs one of these to Yuuto in ''LightNovel/HarukaNogizakasSecret Purezza''. She does this in a skimpy Santa outfit, on the advice of a medical "guidebook" written by her younger sister, who's been working to get the lovebirds together the whole time. Haruka's not very aware of how shocking this is, but Yuuto is.

* In ''LightNovel/{{No 6}}'', Shion checks Nezumi's temperature with a headbutt when they first meet.

* In ''Manga/MonsterMusume'' Centorea demonstrates this to Suu, as Kurusu has a cold and the other girls can't enter his room without risking a lethal infection. It's PlayedForLaughs because not only does Suu not have the same body temperature as a human (being a semi-humanoid SlimeGirl) in the first place, she's apparently unable to tell what temperature he is (or possibly even know what a temperature is, at that point in the story she hadn't even been confirmed to be sentient yet) anyway and simply repeats "42 degrees," because she heard Centorea say that was ''her'' body temperature.
* In ''Manga/DengekiDaisy'' Kurosaki does this to a flustered Teru.
* ''Manga/NagasareteAirantou'': After a day of Machi actually acting like a normal girl (i.e. not pushing herself on Ikuto at every opportunity), Ikuto tells her to hold still and brings his face close. Machi goes into a LuminescentBlush in anticipation of a kiss, but Ikuto's only intention was checking her temperature because of her odd (for her) behavior.

* ''Manga/NegimaMagisterNegiMagi'':
** Negi does this to Asuna while she is under the affects of a LovePotion.
** Chachamaru checks Negi's temperature the same way when he develops a fever near the start of the Magic World arc. In this case, however, ''she'' is the one with the crush on ''him''. She's also nude at the time. As she is a RidiculouslyHumanRobot, this is apparently an accurate way for her to judge temperature.
* ''Manga/{{Naruto}}'': The Mizukage and her teenage bodyguard, Chojuro.

* In ''Manga/ToLoveRu'', Lala does this given any excuse, invariably wearing a NaughtyNurseOutfit.
** Rito does this to Mikan in Darkness while [[LovePotion Celine's flower is on her head]].

* Masaya to Ichigo in ''Manga/TokyoMewMew''.
* Samatarou does this to Tenko in ''Anime/KamisamaKazoku'', not knowing about her crush on him.
* Happens in the ''Manga/SoulEater'' doujinshi, ''Strawberry and Mint''. It's done to hint at the romantic tension between Soul & Maka.

* In ''Manga/ElfenLied'', Yuuka does this to her cousin Kohta to check if he's feverish. Unusually for this trope, Yuuka actually has a secret crush on Kohta, and although she acts nonchalant about touching foreheads together, it's clear to the audience that she's deliberately using the semi-intimate contact to try to cultivate romantic feelings for her. Kouta does this to Nyu/Lucy as well. He's completely oblivious to Nyu/Lucys reaction, apart from noting that her temperature has gone up.
* Aoi to Kaoru in ''Manga/AiYoriAoshi''. He freaks for a second because it looks like she was coming in for a kiss.

* Shion to Nezumi in ''LightNovel/{{No 6}}''. Of course if the preview [[HoYay already has people wondering...]]
* The above trope picture is from the manga adaptation of ''VideoGame/{{Disgaea 2|CursedMemories}}'', as Adell applies this to Friday, the Dimensional Gatekeeper who harbors a massive crush on him. Adell, of course, is highly oblivious to this.
* Happens in ''Manga/HimeChanNoRibon'', when Himeko is caught hiding in her crush's room while disguised as said crush's little sister.
* In the ''Anime/GirlsUndPanzer'', in the "Motto Love Love Sakusen Desu" comic, while Miho is sick with a cold, Hana does this to her to take her temperature..
* ''Anime/RevolutionaryGirlUtena'': Touga does this to Nanami after she [[spoiler:discovers the (fake) truth that they aren't actually blood related]] and starts acting strangely and staying in bed. It makes Nanami very flustered and she protests that she's not a kid anymore. However, unlike most examples, Touga certainly knew exactly what he was doing, and was deliberately trying to incite her feelings.
* Yuu does the to Ayumi in Episode 5 of ''Anime/{{Charlotte}}'' after she starts coughing to see if she has a cold or not.
* ''Manga/PandoraHearts'': Break and Sharon do this to an ill Oz in Caucus Race as does Oz to Alice.

* In ''Manga/ShesMyKnight'', Mogami presses her forehead against Ichinose's forehead to check if he's okay, causing him to blush.
* ''Manga/MyLovelyGhostKana'': In Chapter 7, Daikichi checks Kana's temperature by touching their foreheads together, to see if her fever's gone.

* ''Series/{{House}}'' once does this to Wilson.

* ''VisualNovel/DaCapo'': Junichi does this to his IllGirl sister Nemu fairly frequently to check her temperature, and it really ''is'' a headbutt, as Nemu will infallibly complain.

* Implied in the ''VideoGame/PunchOut'' fanfic ''Fanfic/HomeSick''; Disco Kid notices that Aran Ryan's fever is going down while he is holding him in his arms, tussling his hair.

* In ''Manga/MonsterMusume'' Centorea demonstrates this to Suu, as Kurusu has a cold and the other girls can't enter his room without risking a lethal infection. It's PlayedForLaughs because not only does Suu not have the same body temperature as a human (being a semi-humanoid slime) in the first place, she's apparently unable to tell what temperature he is (or possibly even know what a temperature is, at that point in the story she hadn't even been confirmed to be sentient yet) anyway and simply repeats "42 degrees," because she heard Centorea say that was ''her'' body temperature.

Incidentally, this [[TruthInTelevision actually does work]], and it even works better than using other body parts. Different areas of the body have different temperatures, and if you're checking the forehead, this provides a direct comparison (assuming the performer is at a healthy state). Of course, depending on the relationship between you and the patient, you still might want to consider using other, less personal body parts to do the checking, such as your wrist.

* Mao uses this to check Yuriko's temperature in the ''Anime/MaoChan'' manga. She is unaware of [[FoeYay Yuriko's heart going all]] [[WrittenSoundEffect doki-doki]].

* In ''Manga/MonsterMusume'' Centaurea demonstrates this to Suu, as Kurusu has a cold and the other girls can't enter his room without risking a lethal infection. It's PlayedForLaughs because not only does Suu not have the same body temperature as a human (being a semi-humanoid slime) in the first place, she's apparently unable to tell what temperature he is (or possibly even know what a temperature is, at that point in the story she hadn't even been confirmed to be sentient yet) anyway and simply repeats "42 degrees," because she heard Centaurea say that was ''her'' body temperature.

* In ''Manga/MonsterMusume'' Centaurea demonstrates this to Suu, as Kurusu has a cold and the other girls can't enter his room without risking a lethal infection. It's PlayedForLaughs because not only does Suu not have the same body temperature as a human (being a semi-humanoid slime) in the first place, she's apparently unable to tell what temperature he is (or possibly even know what a temperature is, Suu's intelligence is suspect) anyway and simply repeats "42 degrees," because she heard Centaurea say that was ''her'' body temperature.

* In ''Manga/DailyLifeWithMonsterGirl'' Centaurea demonstrates this to Suu, as Kurusu has a cold and the other girls can't enter his room without risking a lethal infection. It's PlayedForLaughs because not only does Suu not have the same body temperature as a human (being a semi-humanoid slime) in the first place, she's apparently unable to tell what temperature he is (or possibly even know what a temperature is, Suu's intelligence is suspect) anyway and simply repeats "42 degrees," because she heard Centaurea say that was ''her'' body temperature.

* ''Manga/MahouSenseiNegima'':

* Haruka performs one of these to Yuuto in ''LightNovel/NogizakaHarukaNoHimitsu Purezza''. She does this in a skimpy Santa outfit, on the advice of a medical "guidebook" written by her younger sister, who's been working to get the lovebirds together the whole time. Haruka's not very aware of how shocking this is, but Yuuto is.

* [[Manga/HayateTheCombatButler Maria]] did this on one occasion to Hayate while he was sick. This is memorable because it is one of the few instances that [[ChasteHero Hayate]] takes notice of any sort of intimacy and [[LuminescentBlush blushes profusely]]. Maria however, stays completly oblivious to this.

-->'''Taizou''': Not even Adachi Mitzuru would still use that cliché. Aw, who'm I kidding...yes, he would.

* In the ''Anime/GirlsUndPanzer'', in the " Motto Love Love Sakusen Desu" comic, while Miho is sick with a cold, Hana does this to her to take her temperature..

* In an omake for ''VampireKnight,'' Kaname does this to a sick Yuuki. She's not fazed by it; her only concern is getting him sick.
