Higurashi no Naku Koro ni: Happens twice; firstly, at the end of Tatarigoroshi-hen, Keiichi is pushed off a bridge by Satoko (who, after finding him over Rika's corpse, believed he did it), and curses the town to die as he falls. Next morning, he stumbles back into town to find that everyone died of volcanic gases. Satoko (as if she wasn't broken enough) gets this treatment in (the anime only) Yakusamashi-hen, when she finds Rika's mutilated corpse again, falls off a bridge after a lengthy chase (the very same one she pushed Keiichi from) and stumbles back into town several hours later. For bonus points, Satoko becomes a Comatose Canary after this ordeal.
Mion also deserves a mention, due to the fact that the above Satoko example was based on a game-only arc centered on her, Comatose Canary ending and all.
Bleach: Uryuu Ishida is the last survivor of his kind in the world. Six years before the manga begins, the Quincy King carried out The Purge which killed all mixed-blood quincies in the world.

Yhwach is determined to make use of the mysterious ability that Uryuu possesses that allowed him to survive something that should have killed him.
This is an idea that recurs a number of times in Birdy the Mighty: Decode. The most prominent examples are the two seasons' main villains, Shyamalan and Nataru.

The ballad Das Trauerspiel von Afghanistan ("The Tragedy of Afghanistan") by Theodor Fontane, a dramatization of the case of Assistant Surgeon William Brydon (see Real Life).
Tom Clancy did this twice in The Hunt for Red October. (The book, not The Movie.) First a nuclear submarine has a reactor accident that ended up destroying the ship, and only one sailor got out before it sank. Then, later on, a bunch of people were being ferried out to a rendezvous with a different ship by helicopter. The chopper was old, and the transmission exploded, causing the chopper to crash into the ocean within sight of the ship they were supposed to be meeting up with. Only one man managed to get out alive, and was rescued by the ship.

Subverted on Angel when Lindsey briefly believes himself to be the only one left alive by Darla and Drusilla's massacre of the Wolfram and Hart Special Projects division.

Other valleys have similar stories as well.
The Lone Ranger was the sole survivor of an ambush that wiped out a Texas Ranger patrol.
In Paranoia, this is actually a recommended way to win—you can blame all the bad stuff on the dead, and take credit for all the good stuff "without fear of contradiction". But sometimes The Computer is suspicious of Sole Survivors, so it may be better to let a couple live and bribe/blackmail them into backing up your story.
An attrition-based board game, Stay Alive, used the phrase "I'm the sole survivor" in its '80s-era advertisements.
This is one of 3 possible backgrounds you can pick for your character in the series - being the Sole Survivor of a team of marines who got wiped out by Thresher Maws (who are 'bout as nasty as they sound). Can lead to an interesting scene later in the original entry, when you run across another survivor, who had been hunting down a group of scientists responsible for setting up the attack, in order to study the Thresher Maws. If you fail to 'talk him down', he'll execute the last of the scientists, and then say "The vids say that you're the only survivor...who am I to argue?" and then shoot himself. Very dramatic.
Although not named explicitly, the Colonist background also has Shepard as the sole survivor of a batarian slave raid that kills his or her entire family. It's possible to combine this with the Sole Survivor background, creating a Shepard whose pre-Spectre life probably qualifies as cursed.
In Mass Effect 2, if you do everything wrong, Joker will be the sole survivor of the suicide mission.
If you delay starting the suicide mission for too long, then Dr. Chakwas is the only one of the abducted crew who isn't liquefied.
Played for Laughs with mercenary squadmate Zaeed Massani. Talk to him on the Normandy and he'll share some of his many war stories. Practically all of them end with the mission going FUBAR and him being the only one to make it out, getting to keep his dead comrades' pay in the process. His dossier in the Shadow Broker DLC attributes this partly to the fact that he was The Neidermeyer. This is a hint that he's actually a poor choice for a Squad Leader in the end game.
Eve is the only krogan female to survive Maelon's experiments and the side effects. Unless you didn't save his data, in which case she will die.
Two women with Gainaxing tendencies from Super Robot Wars fell to this trope: Selena Recital was the sole survivor of Team Jelba from a Balmarian assault, while Calvina Coulange was the sole survivor from the Ashalley Kreutzer facility when the said facility was decimated by the Furies. And no, they're not expies.
Shirou Emiya in Fate/stay night was the sole survivor of a great fire ten years ago that razed a whole section of the town he lives in and killed almost everyone else living there. A few other kids are mentioned to have gotten out, but they've all moved away to different foster families and Shirou has no contact with anyone else who was directly involved in the disaster. It has left him with a fair bit of Survivors Guilt, and all three routes are dedicated to how he deals with it in different ways. In the Fate route, you eventually get some of the background to the event: Kotomine caused the event by wishing for a distraction from the incomplete Grail, and all the other surviving kids were taken in by the church and converted into living mana batteries for Gilgamesh.
Another Nasuverse example, Tohno Shiki, from Tsukihime, is the sole survivor of the Nanaya demon hunting clan. Not counting his TATARI clones.

Jamil of Valkyria Chronicles II is both the sole survivor of his squad and the sole survivor of his hometown (because it was razed while he was away with the army trying to protect it). Understandably, he has a lot of survivor's guilt and views himself as The Jinx.
Reila "Number 13" from Valkyria Chronicles III is the sole survivor of multiple squads, causing her to be viewed as The Jinx by the regular army. This becomes Fridge Brilliance when you realize she survived when others didn't because she is unknowingly a Valkyria, a race with supernaturally fast and effective healing powers.
One ending of the uncut edition of Ace Combat 3: Electrosphere is titled "Sole Survivor", referring to Fiona Fitzerald, who is the only major character to be still alive at that point. Nemo would count, too, but he is not exactly alive.

If you choose to retrieve the canister instead of saving Jess, and fail to let Gerry get on the boat, Jess will be the sole survivor in Jurassic Park: The Game.

O. Dio, the boss of the Western chapter of Live A Live, is said to be the only survivor of the 7th Cavalry (Custer's unit); several people remark that they thought nobody survived that. When you defeat him, he turns into a horse—in real life, a horse was the only survivor of the 7th Cavalry—and gallops away. The sheriff theorizes that the hate of the dead soldiers had possessed it.
In Guild Wars 2, a distressingly common way for Charr to become gladium, usually either by being badass enough to survive the Suicide Mission, or by becoming a Dangerous Deserter when confronted with something so risky. The player characters don't quite hit this mark, as their sparring partner and only their sparring partner survives the game's intro, but players can recruit gladium of the first type and talk gladium of the second.
Hunk in Resident Evil 2 is the only survivor of the Umbrella cleanup team. His ending portrait in Resident Evil 3 reveals that he's earned a reputation for always being the only member of his team to survive, to the point that other Umbrella employees have nicknamed him "Mr. Death".

In Survival of the Fittest, this is the obvious fate of anyone who wins the game, as the entire point is for the students to kill each other until only one remains. Battle Royale works on a similar system, but is more idealistic. However, Shogo Kawada fits the trope at first, and pretends to be the sole survivor of the Shiroiwa game to aid Nanahara and Nakagawa in their escape.
