Forsythe Pendleton "Jughead" Jones III is one of the main characters created by Bob Montana and John L. Goldwater in Archie Comics who first appeared in the first Archie story, from Pep Comics #22 (December 1941). He is the son of Forsythe Jones II; in one of the early Archie newspaper comic strips, he himself is identified as Forsythe Pendleton Jones III (and in one strip, likely due to continuity error, as Forsythe Van Jones). He has a white sheepdog named Hot Dog and a younger sister, Forsythia "Jellybean" Jones. Jughead (sometimes shortened to Jug or Juggie) is the best friend of Archie Andrews.

Jughead generally has a characteristic wry and sarcastic sense of humor. He is considered a bit of an oddity, but prefers his nonconformism as opposed to going along with others' styles. His many quirks make him the butt of teasing and abuse from Reggie, Veronica, and even other classmates and teachers. Many episodes involve Reggie and Jughead trying to outdo one another with pranks and bets, and Jughead almost always comes out the victor. He is revealed to be extremely clever and creative when necessary and he often takes advantage of Reggie's and his other tormentors' weaknesses (and has fun all the while).  In the earlier comics, a running gag involved various characters trying to discover Jughead's real name, while Jughead thwarted their efforts. In one story, Archie Andrews and Reggie Mantle go to the school office, where a woman tells them that Jughead's real first name is Steve. After Archie and Reggie leave the office, the audience learns that the woman is actually Jughead's aunt who has just lied as a favor to Jughead to help keep his real first name (Forsythe) hidden. In another story (issue #1 of "The Jughead Jones Comics Digest," June 1977) we find out he is named after his ancestor who is an American hero. For a brief time, Jughead started to use his given name in honor of his ancestor. After learning that this ancestor was married nine times, Jughead reverted to his nickname. In the Little Archie series, his real name is revealed by Miss Grundy at the start of class. He also believes his name attracts girls as in a strip,his name was mentioned and it made the girls crazed for him.  Another mystery that follows Jughead's character is the meaning of the "S" on his sweatshirt. This remains a mystery to this day, although many stories have hinted at a meaning. In Jughead #30 (1992), when his psychiatrist, Sara, asked him "why an 'S'?" he replied "I dunno! My third cousin was called skinny..." The triangular banner on the cover of issue 140 of Archie & Friends shows that the "S" stands for Silby, as in Silby High School, which he attended for a few months as a freshman. At one time after his sweater was filled with holes due to what he thought was a moth when it was actually a chemical accident caused in lab class, he reveals that he simply likes the letter S and finds it "compatible," because the letter can stand for "soup, sandwich, steak and all kinds of goodies!" after his friends ask him. Betty rolls her eyes at the explanation and adds, "S stands for "sorry I asked"!" Another theory is that he is a non-conformist so when everyone wears "R" which stands for Riverdale he just goes with the next letter "S"
