JoJo (ジョジョ) é um apelido compartilhado por todos protagonistas principais de JoJo's Bizarre Adventure, derivado da repetição de "Jo" em seus nomes.

No texto do mangá durante Phantom Blood e Battle Tendency, ele é mais usado em referência à Jonathan e Joseph Joestar.

Cada um dos protagonistas também são descendentes da Família Joestar, e por causa disso todos possuem a Marca de Nascença Joestar.

Não-Protagonists
Os seguintes personagens não são protagonistas na série, e alguns nem pertencem à linhagem Joestar. Entretanto, é notável que seus nomes também podem ser encurtados como "JoJo":

Origin
The name "JoJo" was derived at a where Araki and his first editor, Ryosuke Kabashima, had their first meeting pertaining to the series. The two had decided on "Jonathan" as the series' protagonist, however, Araki also wanted the initials to match in a way similar to the American filmmaker, (S.S). They eventually landed on the name, "Jonathan Joestar" (J.J) and thus the nickname "JoJo" was born.

Jonathan was rumored to be named after "Jonathan's Family Restaurant," however, both Araki and Kabashima confirm this was an urban myth that formed among fans back in the day. Araki had also brought up the name during a 2006 interview, but he claims the interviewer had mentioned it and he just went along with it by accident. Their later meetings during Part 2 and Part 3, however, were ironically at said Jonathan's restaurant.
