Percy Jackson Meets Harry Potter by marinatyrell

Percy Jackson just won his own war, and now Chiron wants to send him, Annabeth, Nico and Thalia to a wizard school in England? Not to mention it's called Hogwarts. What kind of name for a school is that? Their quest is to protect some guy named Harry Potter, and stay undercover. No one can know he's a demigod. Well, off to Hoggy-Warts. WARNING: I wrote this when I was twelve, and it has lots of hate towards Harry & Ron in the beginning, even though I love those guys. It's not very good, sensible, or developed! Read at the risk of your own disappointment and disapproval!!

The Big Three Go To Hogwarts [COMPLETED] by HarryFreakinPotter7

Percy, Thalia, and Nico go to hogwarts to protect Harry in his 4th year. Percy also competes in the Triwizard Tournament as a student from Hecate's School of Witchcraft and Wizardry. Draco, Snape, Luna, Hermione, or any other wizards will not be demigods. Only Dumbledore will be a grandson of Hecate. This takes place after Blood of Olympus.

Percy Jackson: Grandson of Voldemort by Poke_Master57

Takes place after the Deathly Hallows and the Blood of Olympus Percy Jackson thought he could finally live a normal life. He was going to fail high school, be the captain of the swim team, spend a whole, normal year with Annabeth. Yup, not gonna happen. Harry Potter has to redo his seventh year at Hogwarts. At least he gets to be with his best friends. Then some new kid shows up and he can't help but be a little jealous. He was the grandson of Voldemort and the girls were just falling at his feet. Even Ginny and Hermione were swayed by this boy. He was a death eater, and Harry could prove it. Luckily for him, the Triwizard Tournament was right around the corner. If the death eater was chosen, it'd be fun to watch him fail. Warning : Ron/Hermione and Harry/Ginny did not happen yet. Second Warning : Sirius, Snape, and Dumbledore are still alive. Just a disclaimer for the whole book : All rights go to Rick Riordan and J. K. Rowling Cover courtesy of @thatgirlariadne

Annabeth Chase the Triwizard Champion by AsexualConfusion

Annabeth was expecting a normal end to summer. She was expecting to end the day with Percy and wait for her father to pick her up. What she got instead was a quest shoved in her face. And not just any quest, no, Annabeth had to become fourteen again, go to a magical school in the past, and protect a boy named Harry Potter from a rising dark lord. Even worse, she had to go alone. Not only that, but Annabeth's quest is made even harder by some arbitrary school rivalry that pits Harry Potter and his friends against her. Because what's normal when you're a demigod?

An Unlikely duo (AF/PJO/HP Crossover) by KeeraKraze79

Artemis Fowl had always known that he was different. He was a 10 year old criminal mastermind who was plotting ways to kidnap a fairy. It doesn't get much more different than that. But he was yet to discover exactly how different he was.... Nico di Angelo was not a happy camper. The war with Kronos was looming and Nico still hadn't managed to convince Percy to visit the Styx. Even worse, Hades had got it into his head that Nico needed to socialize and "learn about his heritage". What's all this about wizards? What happens when two of the world's most socially awkward 11 year old's run into each other at Hogwarts School of Witchcraft and Wizardry? Hogwarts is in for a bumpy ride....

Saving Wisdom and Wizards || PJO x HP by alternativekitkat

Being a half-blood isn't easy, and it doesn't get easier. Of course, fighting in two wars and being drafted into a third doesn't help. But there are those lucky ones. The ones who survive and move on, have families, education, life. Percy Jackson is not one of them. He's a demigod and apparently, a very powerful and hated wizard. Percy is tasked with helping the Wizard World, and protecting Harry Potter, which is hard to do when Harry wants nothing more than to kill him. ~~~ *Completed* Sequel is up! Check out Hidden Wisdom and Wizards :) ~~~ Rewrite is also up! Same title, but with gray cover. I highly recommend checking that out as well! ~~~ Highest Rankings: #1 Percy Jackson #1 Percabeth #1 Annabeth Chase #1 Wizards #1 Dark!Percy #1 Heroes of Olympus #1 Rick Riordan #1 PJOHOO #2 Crossover

[Demigods Quest to Hogwarts] PJO and HP Crossover by ao3isbetterr

Nico, Percy, and Thalia are given a quest that only children of the Big Three can complete... together. They must go, to Hogwarts.

Demigods Vs Magic. by KnightCrawler101

Part 1 of the "Demigods...." Anthology. Demigods and Wizards. Two groups of supernatural ability. So similar, yet so different. Ever wondered, which one would come victorious in a battle to the death? Well, it happened. Their worlds collided head-on, erupting in a swirling inferno no one could have predicted. It was survival of the fittest, the most ruthless. Two sides entered the battlefield, but only one will walk out. Percy Jackson and Harry Potter knew this. And they were ready. To fight, and to kill. "Neither can live while the other survives." Let's see who won, shall we?

Demigods at Hogwarts | the rescue mission ✔ by PiperAngelo

Kidnapped, separated, forced to save the world by condescending gods-Annabeth Chase and Percy Jackson don't need any more immortals on their doorstep, demanding the "please-clean-up-our-mess" service they never offered in the first place. But when Annabeth disappears from Camp-Half-Blood without a warning in late August, Chiron recruits Percy and his demigod companions to hunt her down. They soon find themselves posing as seventh-year exchange students at Hogwarts, and are introduced to a haunted British castle, a deadly Triwizard Tournament, and a boy named Harry Potter. With Hermione Granger determined to uncover Percy's real identity and Professor Dumbledore hell-bent on being as unhelpful as possible, the demigods struggle to navigate a world where everyone can use magic for better or for worse. Percy competes in the Triwizard Tournament with what is perceived as false hope to all his friends, and a belief that victory will lead him to his estranged girlfriend. But dark secrets are unraveled with each passing day, and the demigods all have their own battles to fight. Temptation, cowardice, PTSD and distrust gradually drive them further apart-will they ultimately defeat the sinister force that brought them to this deceit-ridden school? Because Harry Potter is not the only one with an unknown past, and Percy's own roots are tied to his enemy's 𝙧𝙚𝙖𝙡 motive.
