JoJo's Bizarre Adventure is often noted for the amount of casualties and fatalities that occurs throughout the series. The following is a comprehensive list of the deceased (either physically or mentally) from Phantom Blood through the ongoing JoJolion, as well as any other JoJo-related media.
Please note that this list consists primarily of canonical deaths; the deaths of characters from one-shots or light novels not written by Hirohiko Araki listed below may or may not be considered canon.
Becomes a vampire from the Stone Mask and brutally kills everyone in his archaeology group aside from his son. When he begins to go in pursuit of his son in desire of more blood, he is killed by the light from the morning sun.
Killed when Dio puts the Stone Mask on one's face and then pushes him into stabbing his partner. The mask turns the man into a vampire but he soon disintegrates in the sunlight when attempting to suck Dio's blood.
Takes the blow from Dio's knife, sacrificing himself for Jonathan's sake. Dio attempted to kill Jonathan with a knife to activate the Stone Mask with his blood. While Dio becomes a vampire, George admits his mistreatment of his son, then dies in Jonathan's arms.
One late evening, Jack and his date are in Whitechapel district. The girl starts talking about Jack the Ripper (unaware of her date being the serial killer). Jack then reveals his identity and kills her by slicing her neck with a knife.
Zeppeli uses his own version of Sunlight Yellow Overdrive to karate chop one of them in the face, simultaneously killing three more when the body is sent flying into the zombies behind it. Speedwagon crushes one in the head using his sledgehammer. Jonathan decapitates the final one with Zoom Punch.
Defeated by Jonathan. The Ripple sent to him "frees his soul" allowing him to feel human again. He loses his hatred towards the world and is thankful for his chance to meet the honorable Jonathan. Moments before he disintegrates from the Ripple, Bruford gives Jonathan his sword, Luck and Pluck.
Allows his body to be sliced in half by the chains of Tarkus, so that Jonathan could be free and defeat him. He is able to transfer his remaining Ripple energy to Jonathan before dying. Due to Tonpetty's prediction of his death, Will was fully aware of it, and for this motive he dies without regret.
Jonathan kills one by grabbing its head and smashing it into the bars of a window, slicing its head open from the impact. Straizo, Tonpetty and Robert E. O. Speedwagon kill the remaining offscreen, and two are killed by Dio's eye beams.
Destroyed by Jonathan, who uses the last of his strength to crush Wang Chan's head and send a Ripple throughout his body. The impact from the attack sends Wang Chan's headless body flying into the ship's machinery, causing the ship to explode.
Tragically dies from overexerting himself against Wang Chan and Dio, so that Erina and a baby on the ship could be safe. Before dying, he attempts to take Dio down with him by holding Dio's head in his arms just before the ship explodes.
With the exception of Kars, Esidisi, Wamuu, and Santana, the entire clan is killed by Kars. Prior to their deaths, the Pillar Men feared Kars due to his obsession, and planned to have him executed despite his protests.
Murdered by his superior officer in the British Air Force during World War I, who George confronts after discovering the officer was actually a zombie created by Dio. The short lifespans of the men in the Joestar Family is mentioned after George II's death.
One of many who served Dio Brando, and is disguised as a major squad leader in the British Air Force for several decades. After he kills George Joestar II, Lisa Lisa avenges her husband by killing the zombie with the Ripple.
Becomes absorbed into the wall at the site where the Pillar Men were discovered. He was saving a boy who activated a trap from the Pillar Men by touching an embedded diamond in the wall. Spears thrust out of the wall but Mario pushes the boy out of the way and gets pierced in the process, unaware that he just saved his own son, Caesar Zeppeli. The spears then pull Mario into the wall, where he is to be eaten by the Pillar Men.
Joseph knocks out the pilot of the plane these men hijacked with the Ripple so that the plane would crash. Joseph then saves the pilot, Speedwagon and himself by ejecting out of the plane. The hijackers presumably die when the plane crashes.
Kills himself in his battle with Joseph Joestar by overloading his own vampire body with the Ripple. He states that he wanted "to taste youth and go to Hell rather than age pathetically like an old man and go to Heaven", and also reveals seeing Santana almost awoken.
Santana slides out of the vent near the officer and dives into his head through his eyes. Santana enlarges within the man's body causing it to swell up immensely. He later tears himself out of the man's body when it is no longer of any use to him.
Killed by Esidisi when the latter impales the former with his foot. Posthumously, Loggins' body is used by Esidisi to demonstrate his ability, heating the corpse until it boils and simmers from the inside-out.
Evaporates from sunlight exposure after being forced out of Suzi Q's body by Joseph and Caesar's Ripple. Prior to this, Joseph destroyed his body during their battle and reduced him to a brain, thus forcing him to possess Suzi Q before truly dying.
Ultimately defeated by Wamuu due to his overconfidence in close combat. He uses the last ounce of his strength to take Wamuu's lip piercing that contains the antidote to the ring that Wamuu placed on Joseph's heart. He loops his headband through the ring and encases it in a bubble of blood held together by his Ripple, just before being crushed by a slab from the ceiling.
Faces death after being worn down by Joseph's Ripple attacks, with the finishing blow being Caesar's headband causing his body to explode. After being reduced to a head, Joseph gives him some of his own blood to ease the pain. Wamuu uses the last of his strength to destroy a group of vampires who were attempting to kill Joseph before he disintegrates into dust.
Attempts to kill Joseph with the Ripple, which he previously demonstrated when attacking Joseph's knee. However, Joseph reflexively held up the Red Stone of Aja, causing Kars' attack to collide with the stone and unleash a surge of energy deep into the earth powerful enough to jump-start a volcano which shoots Kars into space. Kars attempts to return, but the cold vacuum of space freezes his entire body before he could change course. Incapable of dying, he floated around space helplessly until he desired death, ultimately ceasing thought. While still physically alive, Kars is classified as brain-dead.

He's stabbed to death by Polnareff's Silver Chariot as revenge for raping and murdering his sister. After stabbing J. Geil's tongue and tossing him into the air, his body is left hanging upside down by a gate. In the OVA, he is instead punched into a barbed fence.

He is thought to have died after protecting Polnareff from Hol Horse's attack and being stabbed by Hanged Man. However, Avdol rises again to save Polnareff by defeating Cameo as it is revealed that instead of killing him, Hol Horse's bullet only skimmed his forehead which rendered him unconscious.

In the OVA, Avdol is killed and vaporised by Vanilla Ice.
He, after losing his foot during his fight with Pet Shop, sacrifices himself to save Polnareff in the fight against Vanilla Ice.

He, after being tortured by DIO and having his teeth ripped out, is killed in a car crash caused by DIO, shortly after being forced to run over and kill countless innocent people on the streets of Cairo.
He confronts DIO on his own and is defeated by The World, having been punched straight through the abdomen in a counterattack. Running away from home, his parents never knew where or how he died.

Using the last of his strength, Hierophant Green destroyed a nearby clock tower in order to tell Joseph and the others about The World's ability to stop time.
He kicks Jotaro with The World after being countered with a Time Stop by Jotaro and Star Platinum. However, Star Platinum's fist connects with The World's leg, shattering the Stand and DIO with it. The resulting force and impact causes DIO's head and right arm to explode. What is left of the body is then brought to the Speedwagon Foundation and the blood is used to revive Joseph, after which his corpse (which technically is Jonathan Joestar's) is left in the desert to disintegrate by the morning sun.
He is killed by Red Hot Chili Pepper after taking an attack from the Stand to protect his brother, Okuyasu.

He explodes from Kira's Killer Queen after mistaking Kira's lunch bag for his own and seeing the disembodied hand contained within it.
