Harry goes back in time to his younger self
This seems to be the most asked question lately on Fictionalley.org in the forum "I'm looking for", so I decided to make as complete a listing as possible.
1) Harry's mind goes back in time to his younger self, het (or gen)
a) Post-HBP
b) Post-OotP
c) earlier than OotP or unknown
2) Harry's mind goes back in time to his younger self, slash
3) Someone else sends their mind back in time to a younger self
4) Harry goes back in time bodily to help his younger self
5) Fics with similar themes
## I absolutely love this fic. It's really outstanding and original.
# Great fic, definitely worth a read.
(I won't add either # or ## to a short WIP.)
NR I haven't read this fic - While I have looked at every fic long enough to check it actually fits my list (and if possible to find out pairings and how long it follows canon), there are severals that I only skipped through. And severals where I only checked out the first couple of chapters.
NRC I have done more than just skipping through but I haven't read the complete fic.
new Fic has been added recently
Fics are more or less sorted by "importance". What this means is that my favorite fics, the ones that are better written and complete or updated regularly will always be on top of the list in a category. Fics that I didn't like, deem weird or which are most likely abandoned (and in particular short abandoned WIPs) will be farther down in the listing of their category.
This list most likely isn't complete yet but I'll gladly add anything you can tell me - as long as it fits the parameters:
- It has to be canon-Harry who travels to his past and then alters his own past, either melding with his younger self completely or at least meeting his younger self with the younger self knowing about the older being there. The past actually has to be altered. If Harry travels to the past because he knows he did and thus keeps the timeline correct, it does not count.
- Unless you can give me a good reason why a specific fic should be included, I will not take "Harry travels to an AU"-stories. This is about Harry time travelling! I will, however, accept fics where Harry is thrown into a younger AU-self instead of ending up in his canon-past.
- As for other characters doing the timetravelling, with any characters other than Harry it has to be only their mind travelling back. I only take Harry timetravelling bodily, no others. (For other kind of timetravelling fics, please refer to painless-j's Masterlist.)
Please be so kind and don't just leave a link: leave a summary, pairing (if there is one) and how it fits my list! Rating and Status (WIP, Complete, Hiatus, Abandoned or One-shot) would help as well.
Thanks. :-) And thank you everyone who contributed to this list.

Story starts out promising but then the author had to add in Sirius having been in love with James' sister Zizi who now hides herself and their daughter Hermione under the name of Granger (but they don't recognize each other when they meet again). Remus had been in love with Sirius' sister Ara... To make matters worse, the story is badly in need of a beta.

Backwards Compatible by Ruskbyte. (Or here).
Harry/Hermione. After decades of fighting, the war is over. Voldemort won. The light's last hope is a desperate ploy, concocted by an insane genius, that probably won't work anyway. Now, armed with an experimental tool whose limits even its creator didn't imagine, Harry must find a way to change history for the better and win a war that he's already lost once before.
It has an interesting concept, possibly a crossover with something, but I find the mix of technology and magic a bit weird. Unlike most other of those timetravel-fics which are mostly told from the point of view of older Harry, this is told more from point of view of younger Harry who just happens to have extra knowledge and stuff.
WIP. (Author hasn't worked on this story for 9 or 10 months - though he has written one or two one-shots.) PG-13.
Abyssus Abyssum Invocat by VHDL and continued by Lady Kanko Wildstar. NR

A Boy and his Hat by shreve.
Post-OotP (?). Dumbledore has manipulated the Sorting Hat to drag Harry Potter back from the future to his 11-year old self. Harry is vengeful and ready to kill to protect the past. It's just another independent Harry in the past fic.
WIP. R.
I don't find this fic to be very well written. There are also some weird jumps that don't make much sense to me. And I don't like Harry being that vindictive towards most people.
Undo, Retry by Olafr.
Possibly Harry/Hermione. Lucius kills Harry and this sends him back to his one-year old self...
Original storyline for pre-Hogwarts but unfortunately most likely abandoned right after the Sorting.
Abandoned WIP. PG-13.

Abandoned WIP. PG-13.
Deal with the Devil by Blood-Foxs-Revenge. NR
With the help of a fox-spirit Harry gets to do his fifth year again.
Abandoned. PG-13.
The Seer by Raspberry Jo.
Harry doesn't actually timetravel in this fic. He is some kind of seer who dreams the future before he lives it. It's still young Harry with memories of the future, so for completeness' sake, it belongs here.

And a beta would have helped...
c) earlier than OotP or unknown

Harry Potter: New Beginnings by Seth O. Blade. NR
Harry/Hermione. Harry Potter is gifted with a new chance to stop the war, not only has he got another chance at the war, he has another chance at life. A Harry Potter Time Travel story. Manipulative Dumbledore. Dark Harry (though probably not evil.)
WIP. R.
I didn't read farther than a chapter or two, there were just too many gaps in the background story for me to fully understand how Harry gets everything.
Let's do the Time Warp again by Rorschach's Blot.
Harry/Harem. A potion-accident sends Harry into the past and now he gets revenge on everyone.
Humor. R. Complete.
While I absolutely love his other fic, Make a Wish, this one is a bit too silly to my taste - though it does have a few humorous moments I liked.
Second Chances by Irish Valkyrie.
Post-GoF. Harry/Hermione. The Final Battle has come down to a fight between Harry and Voldemort. But what happens when a freak accident hurls Harry 13 years into the past? Will he be able to fix everything, or are some things just out of his control?
WIP. R.
Story is quite interesting but neither Harry (nor Hermione for that matter who somehow kind of remembers parts of the future as well) act anything like four-year olds.
To Cross the Bridge of Death by swordchucks. NR
Harry/Ginny. Ginny Potter, driven mad by grief after the death of her husband, attempts an impossibly complex and ultimately fatal spell to reverse time. However, she didn't count on one vital detail.
WIP (possibly abandoned). R.
Ashes in Our Mouths by feanor.
Post-GoF.(?) Long ago Harry has defeated Voldemort, only to be called You-Know-Who now. Using a rift in time he ends up in his body just after having defeated Quirrel in his first year. Friendship with Draco.
Complete. PG-13.
I didn't like the fic and didn't really manage to follow it completely as it somehow jumps from one thing to the next, back and forth in time, with little explanations - at least in my eyes.
Circular Reasoning by Swimdraconian.
Due to circumstances beyond his control, Harry ends up in his thirteen year old body with a war and a troubled future on his mind. This fiction is different to others because Harry's body reflects the changes: his body is in between his two ages. And he keeps everything he had on his person when he died and got pulled back through the Veil.
WIP. R.
This fic is quite a bit weird in my opinion, probably a cross-over.
Time Turned by Rheniel.
A single moment of distraction in third year means Harry doesn't notice the time turner - until he jumps and manages to spin it. He's sent back to his eleven-year old self, and doesn't remember... or does he?
Abandoned. PG-13.
2) Harry's mind goes back in time to his younger self, slash
Curse of Fate by Mistress Nika. #
No pairing as of yet. Post-HBP (?). Thousands of years into the future, vampire Harry only wants to join his loved ones in death. However, his curse of immortality is absolute. Therefore he sends himself back into the body of his infant self, vowing to this time refuse eternity. When do things ever go according to plan? Unexpected changes to the timeline, people who aren't as they once were and more send his life spiraling out of his control. Because some things were meant to be.
Pairings: Harry/Snape or Harry/Lucius, Ron/Hermione, Sirius/Remus, past Harry/Ginny.
WIP. R.
The Mirror of Maybe by Midnight Blue. ##
Harry/Snape. Post-GoF. Harry gets drawn into a mirror and during his short stay in there lives several years. When he gets back, he has the memories and reflexes of his future self but still the body of his teenage self.
(This doesn't fully fit the requirements for my list completely as it's not actual timetravel but it has Harry's older mind in his younger body, so I included it.)
WIP. NC-17. (Unfortunately updates are few and far in between but the story is absolutely brilliant.)
No Way Back by Meri. #
Harry/Snape. Post-OotP. Harry gets drawn into a mirror and lives there 20 years, keeping the memories of his other life there and using it to change the future.

Harry/Snape. Post-HBP. With the war over and everyone Harry cared about gone, he decides to use a spell that will take him to a new world where all his loved ones are still alive. However something goes wrong. Instead of a new life, he finds himself starting over.
Very original story. If it continues as well as it's started, it will be an outstanding piece of fan fiction.
Hiatus. NC-17. Chan. (Story isn't abandoned, the author needs to rethink and rewrite parts of it.)
Invictus by Tsurai no Shi.
Harry/Snape. The war has ended, and in the depths of despair, Fawkes gives Harry a second chance at life, but at a price: his sight.

Beyond This Place of Wrath and Tears by talriga. NR
Post-HBP. The war is lost, Harry Potter has long since been killed and in a last desperate attempt Snape goes back in time to just before HBP.
Interesting and original fic. I have only read the beginning as I usually only read Harry-centric but it definitely sounds promising.
WIP. PG-13.
Crossing Bridges by Tien Riu tienriu.
Gen. After the war is lost, in a last desperate measure Remus has to send his mind back to his 11-year old self.
Interesting and quite original.
Complete. PG.
Erasing Time's Tracks by Hahukum Konn. #
Harry/Draco. Post-HBP. Draco Malfoy has run out of options, and he's run out of time. The only way out is to go back to the beginning.
WIP. PG-13.
I don't usually read non-Harry-centric stories but I tried this one and it totally drew me in. It's quite different from most of the other Redo-stories as Draco doesn't know a lot of the major facts and thus can't consciously change them.

Out of Time by Rurouni Star. NR.
Hermione's got a convenient new thing called a timeturner that lets her get to classes in third year. But suddenly, a message from herself has her housing a known convict, and it's not so convenient anymore...
Her Twisted Timeline series is fabulous. Hermione is the time-traveler, but it's not from the older Hermione's POV, but the younger one. Her future memories come back slowly, in flashbacks and all sorts of things. At times it can be confusing, but I think the author does it on purpose; Hermione is truly confused as to what memories are of the present and which are of the future.
Sequel Shattered Moments
And for every small change, there is another, and another, and another... Hermione goes into fourth year with a misbehaving timeturner and the knowledge that there is a dark future to prevent.
WIP. PG-13.

(As it's dimensional travel, story doesn't fully fit the criteria but it's well-written, so I added it anyway.)

Harry Potter and Fate's Debt by intromit. (Or here for the edited, updated version.) ##
Harry/Ginny. Just before leaving for Hogwarts finds a letter from his future self: "Get to know Ginny. Fate owed me." This leads to Harry and Ginny soulbonding the moment they meet at the station before Harry begins his first year at Hogwarts.
The original version goes till the ending of OotP, the new version only is a few chapters so far (end of PoA right now) but as good as the original story was, the edited and corrected version is infinitely better. Not only are most of the spelling errors, etc. corrected, it's also a lot longer and more detailled. Well worth the wait to get the corrected version up to that point.
WIP. PG-13.
(There is an abandoned spin-off by Phoenix Aeternum, Fate's Debt and the Philospher's Stone. As it's abandoned and I didn't even like it all that much, I have not included a link. You can find the story on ff.net and Siye if I remember correctly, though, if you are interested.)
