Even though The Simpsons primarily maintains the status quo, throughout the run of the series, several characters, both recurring and one-time, have died. Additionally, many characters have been jokingly killed off during the Treehouse of Horror episodes.
Soldier eaten by an elephant during the Vietnam War despite Skinner's warning in Skinner's Sense of Snow.
C. W. McAllister died on the Murderhorn mountain in 1928, presumably from altitude sickness as his oxygen was stolen. Abraham Simpson has taken a
bite out of his arm. His body was only found in "King of the Hill".
Waylon Smithers, Sr., died of radiation poisoning. When he was younger Homer Simpson discovered his body, presumably a while after his death as it had quite substaintually decayed. Homer had flashbacks of the event when he was hypnotised in "The Blunder Years". Mr. Burns later showed the Simpson family, as well as Chief Wiggum and Waylon Smither Jr., the footage of his death. Showing that he had died saving Springfield.

Dr. Marvin Monroe, It was originally thought that Marvin Monroe was dead. In "Who Shot Mr. Burns? (Part Two)", the hospital Burns attends is called The Marvin Monroe Memorial Hospital, and since that, his gravestone has been seen. Most prominently, in The Simpsons 138th Episode Spectacular one of the trivia questions asked was "Which two popular characters have died in the past year?" With the answer being, "If you said Bleeding Gums Murphy and Dr. Marvin Monroe you were wrong, they were never popular," indicating he was dead. However, Marvin Monroe re-appeared ten years later in the episode "Diatribe of a Mad Housewife", saying that he has been "very sick".
A Man falls into in a sea of lava reaching for a pay phone to answer Bart's call in "Bart vs. Australia".

Mother bird, Bart Simpson accidentally shots the bird with Nelson Muntz's BB gun. The gun had a crooked sight, which meant that despite the fact that Bart was aiming away from the bird, he still killed it. Bart had to look after her eggs, in "Bart the Mother".
Maude Flanders, died in "Alone Again, Natura-Diddily" when she was knocked off a racetrack grandstand by t-shirts shot from cannons.[1] She was killed off due to problems with her voice actress Maggie Roswell. Maude's death is considered to be the most show-changing death, and affected Ned Flanders in several episodes after the incident.

Poochie, died on the way back to his home planet during an episode of the Itchy & Scratchy Show in "The Itchy & Scratchy & Poochie Show". He was killed off due to immense unpopularity. However, he still appears as a background character from time to time, so he may not actually be dead. For example, he appeared in non-canon segment "The Terror of Tiny Toon" in "Treehouse of Horror IX".
Note: Treehouse of Horror deaths are kept separate due to the nature of Treehouse of Horror episodes. Treehouse of Horror episodes aren't continuous with the rest of the series, giving the writers the possibility of killing off important characters without having to create a replacement or write them out of the series. (e.g. in Treehouse of Horror XV, Homer obliterates Springfield, but the series continues on.)
