* PlayedForDrama in ''WesternAnimation/KungFuPanda'': Shifu's love for his adoptive son, Tai Lung, blinded him to both Lung's [[StartOfDarkness growing personal issues]] and the possibility that Lung wasn't cut out for being the Dragon Warrior. He filled Tai Lung's head with dreams and put him through decades of brutal training... then had no answers when Oogway frankly stated that Tai Lung was not the Dragon Warrior. [[RoaringRampageOfRevenge Tai Lung's response to that]] was disastrous.

* In ''WesternAnimation/DannyPhantom'' fanfic ''Fanfic/{{ResurrectedMemories}}'': [[spoiler: At one point Ember is so lovestruck she thinks she can hide her true identity from Danny indefinitely even when Kitty points out how difficult that would be especially if the two ever have kids, sure enough it doesn't take long for her to let her guard down enough that she unknowingly changes into her ghost form while kissing Danny]].

* Neo in the ''Film/TheMatrixReloaded'' [[spoiler: sacrifices the fate of Zion to [[AlwaysSaveTheGirl save his girl Trinity]] from certain death made all the more painful when she dies in the last movie anyway. Although ThePowerOfLove is what makes Neo so unique as TheChosenOne so maybe it's fitting though... kinda disingenuous for a MessianicArchetype though]].

SisterTrope to LustMakesYouDumb, the {{lust}} based counterpart. Subtrope of TookALevelInDumbass. Granted, Dumb might be better than [[LoveMakesYouCrazy the]] [[LoveMakesYouEvil alternatives]]. Can (and probably will) lead to GibberishOfLove. See also LoveCanMakeYouGonk, DistractedByTheSexy, and RevengeRomance.

* In the ''Literature/{{Dragonlance}}'' novels, Laurana's love for Tanis Half-Elven causes her to make the incredibly stupid decision [[spoiler: to trust her ArchEnemy Kitiara]].

* In ''Manhua/GoddessCreationSystem'' Xiaxi caused the two Wang Pu brothers to fall in love with her by carefully crafting a specific persona designed to appeal to them both and then nudging events around to make herself look as good as possible. That's all well and good, but there are massive holes in her plans that the story actually does acknowledge, but it's implied that the brothers are so enthralled by that point that they never think to question how implausible everything was or how her behavior doesn't actually match her personality very well.

* Mentioned in ''Series/{{Castle}}'', shortly after Alexis and Pi break up:

* While it might be a better example of Lust Makes You Dumb instead of love, people who live in more rural areas will tell you that you're most likely to hit a wild animal crossing the road during the spring. Since spring is mating season when most female mammals go into heat, it would start to appear that the idea of mating starts to override an animal's basic common sense and self-preservation.

* The Red Knight in the chess based ballet ''Theatre/{{Checkmate}} falls hard for the Black Queen, to the point he throws a sword fight against her (that he's on the verge of winning) because he cannot bring himself to kill her. [[spoiler: She literally stabs him in the back.]]

* ''VisualNovel/NineHoursNinePersonsNineDoors'': Junpei and Akane are reasonably intelligent people, except when they're around each other. [[spoiler:Maybe that's why Akane abandoned him when [[VisualNovel/VirtuesLastReward she went off to save the world from Radical-6]]]]. This trope is a major plot point in Akane's backstory, [[spoiler:where it nearly gets her killed and then saves her life]].

* ''ComicBook/AstroCity'': The brilliant Mock Turtle is blinded by love for his childhood sweetheart Lucia, who he constantly imagines as an innocent girl to be sheltered from his roguish life. She, in turn, easily exploits his intellect and engineering talents for her own gain.

Subtrope of TookALevelInDumbass. Granted, Dumb might be better than [[LoveMakesYouCrazy the]] [[LoveMakesYouEvil alternatives]]. Can (and probably will) lead to GibberishOfLove. See also LoveCanMakeYouGonk, DistractedByTheSexy, and RevengeRomance.

* In ''WesternAnimation/RockosModernLife'' episode, "An Elk For Heffer" when Heffer falls in love with an Elk named Elkie, [[BrainWithAManualControl his heart starts influencing his actions]] and starts pulling switches labeled "Look Stupid", "Stumble Over" and "Forget Name".

* Sakura Haruno from ''Anime/{{Naruto}}'' in regards to Sasuke, it’s worth noting fans actually forget Sakura is a [[TheSmartGuy smart cookie]] but whenever her SingleTargetSexuality comes up, it renders her IQ somewhere around toddler level. At 12 years old, she was willing to leave her parents and village for a boy she’s hasn’t so much as had a proper conversation with and even three years later, she was willing to lie to her best male friend (Naruto) telling him that she loves so he’ll stop chasing after Sasuke. Oh, and when that fails miserably, Sakura tries to stop Sasuke herself (also failing because she “wuvs him too much”) nearly getting herself killed by Sasuke and is saved by her teacher and the boy she friend-zoned. Thankfully she got some CharacterDevelopment during the Ninja War and for once stops caring about Sasuke being more concerned with Naruto dying... [[spoiler:then Sasuke has one last HeelFaceTurn and Sakura [[EasilyForgiven forgives him completely]] despite him literally knocking her out again and later actually asks to join him when Sasuke leaves Konaha]].
** To be fair to Sakura, ''many'' characters in Naruto suffer from this, like Karin who arguably has it worse than Sakura and even the sensible Hinata nearly gets herself killed needlessly over Naruto.

* Played with in ''Series/{{Frasier}}'', where Frasier is constantly doing face-palmingly stupid things whenever he gets into a relationship with a woman and directly ignoring his very own psychiatric advice... and ''he knows it'', and can't help it, and constantly hopes his romantic plans won't blow up in his face this time, no matter how many times his GenreSavvy little brother reminds him how badly he suffers from this trope, with his stupidity probably reaching a zenith in "Don Juan in Hell". This is just one aspect of pretty much the very core of Frasier's character -- being brilliant at giving other people advice, and terrible at following it himself.

* ''WesternAnimation/SouthPark'': In "The Succubus", the typically GenreSavvy Chef falls for a succubus, who has this effect on him, albeit via MoreThanMindControl on her part. It takes the boys exposing her to get him back to reality.

* ''ComicBook/ScottPilgrim'' plays with this trope. Granted, [[IdiotHero the titular character is already kind of dumb]] but one can also see this trope in Knives Chau.
* Monkey Khan in ''ComicBook/SonicTheHedgehogArchieComics'' gave up the Power Ring he uses to make sure that Eggman or the Iron Queen can't control him due to his mostly cybernetic body. [[spoiler: He lets himself be controlled by Eggman just so Mecha Sally won't die, despite the fact that Mecha Sally has no remorse or inhibitions and will happily kill him despite the brief relationship Sally and Khan had.]]
