The self-inflicted version of Accidental Murder: a character unintentionally kills themself, typically by accident but also by a plan gone awry.
A common portrayal of this trope is when a character who was planning on killing themself changes their mind at the last minute, only for it either to be too late (they already swallowed the lethal dose of medicine and can't throw it back up) or for an accident to occur (stepping out of a tub holding a toaster only to slip on some water and fall right back in). In both cases, these suicides are also examples of Death by Irony, with the latter in particular being mined as a source of Black Comedy in which the victims either have a deathgrip on the Idiot Ball or are just simply Too Dumb to Live.
Engaging in risky behavior that can lead to one killing themself if not done correctly, like autoerotic asphyxiation is another way this trope has been used. Reckless Gun Usage in particular has also claimed more than its share of accidental victims.
A variant of this trope exists in which a character (usually The Chessmaster) did in fact want to kill themselves, typically as part of a Death Is the Only Option gambit or Suicide, Not Murder scheme. However, they had no intention of staying dead for too long. Unlucky for them, something goes wrong and they remain dead as a doornail. If they were also a villain, then Hoist by His Own Petard and Karmic Death are in full effect.
A fatal accident simply happening to a character is not enough to be this trope. The character must have had some hand in their own demise.
Can overlap with Accident, Not Murder. Contrast Suicide, Not Accident and Bungled Suicide, both of which are inversions. Also contrast Make It Look Like an Accident, in which a character murders another, but tries to stage it as a freak accident. If they try to stage it as a suicide, then it's Never Suicide. Murder by Suicide and its subtropes are closely related. However, key difference is in Murder by Suicide, someone or something else coerces, compels, or tricks a character into killing themself (and all examples like this should be listed there).
Given that Death Is Cheap in most video games as a game mechanic, avoid adding video game examples in which the death is incidental to the game itself, i.e. just the fact that the player character or an AI controlled teammate can unintentionally kill themselves. Video game examples should either be part of the narrative/story or specifically lampshaded in-game.
As a Death Trope, all spoilers related to character death will be unmarked below. Beware.

This ages him up and turns him into a One-Man Army, whose power, Pitou notes, rivals that of Mereum, a Dark Messiah Physical God and killer of Netero, the leader of the Hunter Association. At the end of the fight, Gon is a literal husk of a person on death's doorstep. It takes Killua's sister Alluka, who has a Make a Wish nen ability via Nanika that allows her to warp reality, to heal him. But even then, it's not enough to restore Gon's nen abilities.
- Puella Magi Oriko Magica: After learning the truth about witches (namely, that they are former magical girls), Sasa Yuuki crushes her Soul Gem in her hand, resulting in her death. It's suggested that she did not realize that Soul Gems actually held their souls and thought that crushing her Soul Gem would only stop her from becoming a witch, which makes her death accidental.
- The Grand Finale of the Kyoto Arc of Rurouni Kenshin shows Makoto Shishio getting to his max to finally defeat Kenshin Himura. But before he could give Kenshin the final hit to kill him, Shishio's body shuts down since he pushed himself to fight Kenshin for 30 minutes, way over his 20 minute limit (he can't fight at his max for over 20 minutes since doing so causes his blood to boil). This leads to his inevitable death by Spontaneous Human Combustion.
- Yo Kai Watch: When Manjimutt was still a human, he got drunk to deal with the pain of being fired and bumped into some heavy planks, which crushed him and a passing poodle to death. This is the reason he is a dog with a human face as a Yo-kai.
- His Legendary counterpart, Dandoodle, also became a Yo-kai due to a similar accident.
- In the "Voodoo Mansion" back-up story in Lori Lovecraft: Into the Past #1 (which takes place in the same continuity as Lori's adventures), it is revealed that one of the souls residing in the mansion is Patrick, who accidentally strangled himself while attempting autoerotic asphyxiation. To avoid shame, his family removed the pornography before reporting his death. His death was ruled a suicide and his body turned into an anatomy skeleton.
- Corpse Bride: Barkis is wanted by the dead for tricking Emily into marrying him, stealing her fortune, and then murdering her, however they cannot touch him since the dead are unable to harm the living. After some Evil Gloating, he casually takes a sip from a cup placed on the altar. Unfortunately for him, the cup contained the poison which Victor was supposed to drink during his fatal marriage ceremony to Emily and Barkis is instantly killed, leading him to a Fate Worse than Death at the ghosts' hands.
- Kung Fu Panda 2: When Lord Shen is trying to stab Po, he unintentionally cuts a rope that holds up his largest cannon (that he invented himself!) and he is crushed to death.
- Mary and Max: Vera, who is depressed about her husband's death, grabs what she thinks is some Sherry wine. It is actually embalming fluid, and she dies shortly afterwards.
- Soul: Joe is excitedly talking on the phone about how he finally got a gig and narrowly (and obliviously) dodges a bunch of dangers. Then he accidentally falls to his death into a manhole, which sets off the movie's plot.
- Tangled: Of a sort; when Eugene cuts Rapunzel's long hair, Gothel clings to the strands in desperation as they lose their magic and she rapidly ages until she dies. Keep in mind that it had been shown before (albeit briefly) that Gothel will age slightly if she touches Rapunzel's hair if it loses its power.
- Tarzan: During the final battle, Clayton gets tangled in a mass of jungle vines and tries to hack them away with his machete, but one vine gets caught around his neck and he ends up accidentally hanging himself.
- In the French film Delicatessen, Aurore spends the entire movie trying to kill herself, but her attempts are always thwarted leading her to get more and more elaborate with her attempts until she's building full-on Death Traps. Her final one includes a combination of swallowing pills while facing a gun set to go off, while she stands with her neck in a noose, with the gas on and a lit Molotov cocktail just under her. Subverting all expectations, she only dies because her husband, not knowing what she's doing, enters the room and turns on the light, igniting the gas and blowing them both up in the process, making this an Accidental Murder and Accidental Suicide twofer.
- Inception: Death Is the Only Option variant. Upon their return to reality after spending a lifetime together in Limbo, Mal remains convinced that they are still dreaming and that she and Cobb need to wake up by killing themselves since in dreams this is the only way out. She leaps out of hotel window and plummets to her death. While she did intend to kill herself, she didn't think doing so would actually mean she'd be dead given the logic of dreams. The Reveal that she was Cobb's first inception success story, as he planted the idea that her world isn't real when she refused to leave Limbo, makes this also overlap with Psychic-Assisted Suicide.

He has a pregnant, very Catholic girlfriend who he does not want to stay with and is being pressured by his family and hers to marry her. He even asks former priest Frank Jr. if The Pope would give him an exemption. When he starts climbing the bridge he is drunk and acting more recklessly than usual, going on a rant about Tony's lack of care for him, which all points to him reaching a Despair Event Horizon. However in the end, Bobby C. slips off the bridge and falls to his death; he does not jump.
- Spider-Man: In a last-ditch attempt to kill Spider-Man, the Green Goblin summons his bladed glider to fly at the hero. Spider-Man dodges the attack, and the glider impales the Goblin instead. It is later discussed in Spider-Man 3 that "he died by his own hand".

- In Discworld, the Ankh-Morpork City Watch have a category labeled "Suicide" for some deaths, usually listed in the police report alongside the lesser offence of "Being Bloody Stupid", to conclude reports on the deaths of people who behaved in such spectacularly stupid and heedless fashion as to precipitate their own deaths. A typical Suicide might involve somebody walking into the hardest pub in town, announcing themself as "Vincent The Invulnerable", and challenging anyone to prove them wrong. A close second might be the vampire who took a job in a pencil factory.
- In the novel Haunted by Chuck Palahniuk, the short story "Guts" mentions in passing that some public health officials believe that the recent spike in teen suicides was in part caused by auto-erotic asphyxiation gone awry.

- CSI: NY: At least twice.
- In the season 3 episode "Cold Reveal", the team investigates the death of Toby Finch, who was found dead in a church with angel wings strapped to his back after seemingly falling from the sky. Initially, Toby's friend and girlfriend are seen as suspects but further investigation reveals what really happened. Toby, obsessed with becoming internet famous, drunkenly attempted to catapult himself off a roof, expecting that his artificial angel wings would help him soar across the sky like a hang glider. To ensure this, he pre-cut the bungee cords on his safety harness, thinking that the force of the catapult would fully disconnect them. Unfortunately, they held faster than he expected, giving him such severe whiplash that his neck snapped in two places killing him before he even fell through the church's paned window. Mac surmises that the only crime committed was the victim's misdirected ambition.

- In the Diagnosis: Murder episode "Murder By Remote Control", a computer expert who had lost his son in a failed operation sought revenge on those he blamed for his son's death by using his computer skills to murder their children.

It's eventually revealed that it was the other way around: the deceased had been slowly poisoning his partner with arsenic in order to get his half of the business. He also had a bad liver, so when his partner gave him the blood transfusion, the arsenic in his partner's blood killed him almost instantly. As Quincy put it, if the victim hadn't tried to kill his partner, he wouldn't have died.
- Red Dwarf:
- This was how Rimmer died in the first episode. He repairs a drive plate improperly, causing it to leak radiation and kill everyone on the ship (except for Lister, who was in stasis at the time), including himself.

- Six Feet Under: The season 2 episode "Back to the Garden" opens with a man going about what seems to be a daily routine of some autoerotic asphyxiation.

- In Tiger King, Travis pointed his new Luger at Joshua and claimed that, with the clip out, it could not fire. He demonstrated by putting the barrel to his own head and pulling the trigger.

(While Travis was visibly depressed and self-destructive, Joshua maintains that Travis was not actually intending to commit suicide at the moment.)
- In Board Game Online, death comes fast and often and is a key component of getting through the game. Naturally, it's possible to accidentally kill yourself through certain actions. A common example is when one player pulls a gun on another player. If the target has Hypno Goggles, they can use them during the target selection phase and make the shooter shoot himself instead. Interestingly, the game did not start off with Death Is Cheap, as it used to be extremely difficult or expensive to prevent dying despite how frequently it came. Later updates made this much more forgiving.
- Team Fortress 2 will lampshade if a player accidentally dies by fall damage (without another player being the cause) in the form of "X fell to a clumsy, painful death" in the killfeed.
- Lampshaded in the Unreal series, especially the Tournament games, where regardless of the circumstances of the suicide (player-triggered via console command or self-inflicted damage), the game taunts the player for doing the deed.

- King of the Hill: In "High Anxiety", this is ultimately the answer to the murder of Debbie Grund, Buck Strickland's former mistress. Debbie wanted to kill Buck for going back to his wife Miz Liz, so she hid in a dumpster with a shotgun and waited for him to pass by. After a while, she got hungry and went to go get some food. She returned to the dumpster but found it too difficult to climb inside while carrying both the shotgun and her food, so she put the shotgun in first. When she climbed in herself, her foot accidentally tripped the hammer and caused the shotgun to fire, killing her.
- The Ren & Stimpy Show: Implied in "No Pants Today". Victor and his father laugh after they kick Stimpy out of their car, and because of this distraction, they drive off a cliff and their car explodes offscreen. It's left unclear if they survived or not.
- The Simpsons: "Homer's Enemy" is all about how Frank Grimes is driven insane trying to figure out how Too Dumb to Live Homer managed to succeed while he's had to struggle through life. Eventually, Frank cracks and starts acting like Homer, doing reckless things and shrugging off the consequences because "I'm Homer Simpson!" It all leads to him electrocuting himself by disobeying the "Do not handle without gloves" sign at a panel with electrical cables.
- South Park: Resident Butt-Monkey and The Chew Toy Kenny does this a lot:
