Word of warning though: Fanfiction is a slippery slope into a very very deep hole. There are some great stories and then there are some absolute tropey tales. A couple of things to note before we jump into the best Percy Jackson fanfiction:
The following recommendations are based on you being familiar with the official and original series of The Lightning Thief: Percy Jackson and the Olympians by Rick Riordan. There are many MANY more books that come from this but The Lightning Thief is where it all started. If you are not familiar with this book, click on the link above and buy the book right now. By the whole Percy Jackson and the Olympians series. It is brilliant and worth it. Fanfiction can be One-Shot, Ongoing, Incomplete, or Complete AU means Alternate Universe with some variation to the original Canon storylines Not all Fanfiction is Character Loyal; some is OOC (out of character) Not every relationship is True Love–eg. There are as many pairings of Percy with other characters as there are pairing Percy with Annabeth Fanfiction ranges from ‘All Ages’ to ‘Adult Only’. While the core series is child-friendly, fanfiction doesn’t always play by the same rules Final warning: Fanfiction is a Rabbit Hole that will take you to Hades and then some. Be prepared to lose time as you explore the creative minds of the most avid fans.

One-Shot Percy Jackson Fanfiction
The Torch of Hestia by driftingskies
Takes place before The Lost Hero and after The Last Olympian. It has a great start, true to the feel of Riordan himself. Hestia’s Olympic Torch is missing and she asks Percy and Annabeth to help find it. Action-packed and with a core fight scene, this is a short but sweet start to your fanfic journey.
Honey, Let Me Sing You a Song by HecateA
HecateA seems to specialise in one-shots; from Percy Jackson to Harry Potter, and a few other popular fandoms in between. Her stand-alones are sweet little insights into the characters, which is exactly the kind of fanfiction you want. Honey, Let Me Sing You a Song is one of my faves because it is a romantic play with Aphrodite and touch of music. As a bonus, I also recommend A Third of Life, featuring the best mum of all: Sally Jackson.
Incomplete or Ongoing Percy Jackson Fanfiction
Son of the Western Sea by Mac Ceallach (6 Chapters)
Even though this one is incomplete and possibly abandoned, what is here is enjoyable. I especially love the bringing in characters from other mythologies like Shinto and Hindu. Plus, this has a far deeper character development for Percy.
Gambit’s Refrain by paradoxed (4 Chapters)
If you’re still looking for some Artemis love, paradoxed has an Artemis/Percy Ship waiting to sail. This one is positively lovely. However, I will warn you now–it will break your heart.
Characters Beyond Percy Jackson
Firsts by shes.a.shy.one
Stretching out from Percy’s immediate world, Firsts is completely focused on Calypso and Leo. It is filled with romantic moments and all the firsts of a budding relationship.
Obviously by ThePraetorLady
Another story looking at the characters who fill the Percy Jackson universe; this time we are visiting Reyna and Jason, during their college years. It has the usual pairings and romance but quite a bit of fun with friends as well.
The Coming of Nico di Angelo by ninjagirlmai
And now for something a little different: A Percy Jackson/Harry Potter crossover. This is common in fanfiction when fans dream of their favourite characters meeting across multiple universes. I have a soft spot for Nico and placing him in Hogwarts gives him a fantastic opportunity for his better qualities to shine. Chapters 1-43 are the complete story; Chapter 44 and onwards are embellishments.
With the Lights On by nikkiRA
On the other hand, if you want to escape all the fantasy and just dive straight into the relationships and characters, there is no better place to start than with Nico di Angelo. That boy needs some love! And yes, Will Solace is there too.
When Everything Goes Wrong
Purgatory by BloodRedDemon on FanFiction
For a slight horror touch, let’s pretend Percy didn’t come back from Tartarus unscathed. He has come back but it’s not quite the same. And I like a darker twist to things.
Percy Jackson and the Prison of the Gods by Project Phoenix Agent 003
No, Annabeth!! How could you?!? How could you choose Luke over Percy?!? Wait, this is fanfiction. Anything is possible. And if you ever wondered what the Percy Jackson Universe would be like IF Kronos had won, then read on.
Change One LIttle Thing and That’s How you Get AU
Ocean’s Wings by lyricalgurl8
It wouldn’t be a ‘best of Percy Jackson fanfiction’ if we didn’t include a gender-switch. This one has Percy as female and a bit more interaction with Luke. I think the biggest difference to Percy here, besides the gender-switch, would be the smarts–Percy now has the wisdom of Athena as well. And that’s … well… interesting.
Grim Olympian Tales: House of Flickering Candles by Felicity Dream
I love Grim fairytales and all the shadows that lurk with them. There is something delicious about the dark potential of Percy in the world of Godfather Death. Poseidon has left Percy in the care of Hades, as a way to appeasement His Sulkiness after the Broken Oath.
Champion of the Sun (complete) by Avarianus
This is so good, it has two sequels, Trials of the Sea and Harbingers. It starts with Apollo raising Percy as his champion, and already you know that won’t bode well. There is far more involvement from Artemis and her Hunters but the highlight for me will always be the interactions with Apollo. I’m a simple nerd.
Thalia Grace & the Olympians: The Lightning Thief by advictorem
Because maybe, just maybe, the best Percy Jackson fanfiction involves Thalia NOT being royally screwed over by her own father.
Son of Chaos by kevin1984
Even the best-laid plans can throw you a curve-ball. And there is nothing worse than giving it your all and receiving no appreciation for it. For this AU re-telling, Perseus loses it all but is allowed to re-do everything–this time not as the Son of Poseidon but as the Son of Chaos.
The Legacy of Asgard by Anaklusmos14
Another crossover of sorts, however, this one is still within the same Universe; just a different mythos. While we have loved Percy Jackson and the Olympians since the beginning, my entire family was extra excited when Riordan explored other mythologies and legends like Ancient Egyptian and Norse Mythology. The Legacy of Asgard is a bit like that, bringing Percy into the Norse family while still interacting with the Olympians. A beautiful blend of worlds and it is balanced so well with the characters.
Shift to Ancient Times
A Crown of Golden Leaves by the evilteddybear
The best Percy Jackson fanfiction doesn’t need to stay in the modern world. For some fans, the appeal lies in the history and mythos surrounding these legends; not surprising since they come from the creative mind of a history teacher! Placing Annabeth and Percy in Ancient Rome is a little bit out of the usual fanfiction but it works with both the storytelling and the politics of the time.
Altered Destinies by Anaklusmos14
The Ancient Greeks were very fatalistic in their ideals of destiny and prophecy. The concept of AU would be easily accepted within many Greek Tragedies, especially when considering whether a horrible twist in one’s childhood could prevent the fulfilment of one’s destiny. In this story, Percy is orphaned and abandoned on the streets by the age of 10. Despite his bitter view on life, he is still ‘touched by the gods’.
Lord Perseus Child of Rome by Anaklusmos14
Part of the appeal of Percy is his ‘demi-god’ status. As a demi-god, Percy still retains some of his humanity, allowing for character flaws and risks to be taken. Move him to an AU where he is a fully-fledged god, and you still have the flaws that come from mythology (because we all know the gods are messed up) but you have an extra level of power to consider too. I know I have already referenced one story from Anaklusmos14 but this is worthy of adding to the list.
Keeping it Real (even with Fanfiction)
Our Bedroom After the War by Rocio Kristal Freytes Martin
This is a very real and almost tangible Percy Jackson fanfic that directly addresses the issue of PTSD; which makes a lot of sense when you consider everything Percy and Annabeth go through in the series. Now, remember: just like Hades, it is easy enough to enter the world of Percy Jackson fanfiction. The hard part is coming back out again.
