Kenneth "Kenny" McCormick,[6][7] voiced by Matt Stone, is one of South Park's main characters, along with Eric Cartman, Stan Marsh, and Kyle Broflovski. He first appears in the short films both entitled The Spirit of Christmas in 1992 and 1995. He is voiced by Mike Judge in the feature film South Park: Bigger, Longer & Uncut and Eric Stough in "The Jeffersons", "Lice Capades", "Mysterion Rises", and "Turd Burglars".

Kenny is most famous for dying in almost every episode in the first five seasons of South Park. He is also easily recognizable for almost always wearing an orange parka, or just having his face hidden, that covers most of his face and muffles his speech. In "Mysterion Rises" Kenny, who is revealed to be the superhero Mysterion, reveals that he has the power of immortality, in a sense, and that he just wakes up in his bed after having died. He is then upset that his friends never remember him dying, and even kills himself in front of everyone to prove himself.

The character was killed off the show in the Season Five episode, "Kenny Dies", but returned in the following season, at the end of "Red Sleigh Down" and has since been a regular character; however, he now only dies occasionally. In most of the episodes in the tenth and eleventh seasons, he tends to recede into the background, though this tendency seems to have ended with the Season Eleven finale. Throughout the tenth, twelfth, eighteenth, nineteenth, twentieth, and twenty-third seasons, Kenny did not die once. Kenny died three times in total in Season Thirteen, five times in Season Fourteen, and once in seasons fifteen, sixteen, twenty-one and twenty-two.
