Even though The Simpsons primarily maintains the status quo, throughout the run of the series several characters, both recurring and one-time have died. These deaths are usually permanent and said characters stay dead, but there have been occasions where some of these characters end up returning with little to no elaboration. Additionally, characters have been jokingly killed off during Treehouse of Horror episodes.

Season 10

  • Pinchy (Homer Simpson's pet lobster) - accidentally got cooked to death when the bath water he was in was too hot. An extremely upset Homer ate Pinchy later at dinner in "Lisa Gets an "A"".
  • Red Barclay - died after a beef-eating contest. Dr. Hibbert, a partner of the steakhouse, says he died of beef poisoning, although it was "probably from some other restaurant" in "Maximum Homerdrive".
  • Mother bird - accidentally got shot by Bart 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".
  • Many birds - presumably killed by Bolivian Tree Lizards in "Bart the Mother".

Season 11

  • Maude Flanders - died in "Alone Again, Natura-Diddily" when she was knocked off a racetrack grandstand by t-shirts shot from cannons.[2] 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.
  • Cornelius Chapman (the only man in Springfield older than Mr. Burns (at 108 years old)) - died onstage from a heart attack after getting a kiss on the cheek from Britney Spears. Fittingly enough, he was receiving an award for Springfield's Oldest Man in "The Mansion Family".
  • The Laramie Cigarettes Team - died when the helicopter exploded at the hands of a Tomacco-addicted sheep (who was the only survivor) in "E-I-E-I-D'oh".
  • Duffman - died when Moe put a sticker over his face in "Pygmoelian". However, Duffman is still alive, as he is portrayed by several actors.

Season 12

  • Man Having Operation - died when a tennis ball landed in his open chest after Dr. Hibbert decided to operate on him outside in "Tennis the Menace".

  • The Only Woman for Moe - hung herself after thinking there was no man for her in "The Blue and the Gray".
  • People On Airplane - presumably died in a plane crash when Patty and Selma remove their smoke and ash from their hair and caused the plane to crash in "The Blue and the Gray".

Treehouse of Horror deaths

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)
