Ed, Edd n Eddy is an animated television series created by Danny Antonucci for Cartoon Network. The series revolves around three friends named Ed, Edd (nicknamed "Double D" to avoid confusion with Ed), and Eddy—collectively known as "the Eds"—who are voiced by Matt Hill, Sam Vincent and Tony Sampson respectively. They live in a suburban cul-de-sac in the fictional town of Peach Creek along with fellow neighbourhood children Kevin, Nazz, Sarah, Jimmy, Rolf, Jonny, and the Eds' female adversaries, the Kanker Sisters, Lee, Marie and May. Under the unofficial leadership of Eddy, the trio frequently invents schemes to make money from their peers to purchase their favourite confection, jawbreakers. Their plans usually fail, leaving them in various, often humiliating and painful, predicaments.

Antonucci, an adult cartoonist, was dared to create a children's cartoon. While designing a commercial, he conceived Ed, Edd n Eddy, designing it to resemble classic cartoons from the 1940s–1970s. When pitching the series to Nickelodeon, the network declined to give him creative control, a deal to which Antonucci did not agree. He then pitched the series to Cartoon Network. A deal was made with the network to commission the series under his control, and it premiered on January 4, 1999. During the show's run, several specials and shorts were produced in addition to the regular television series. The series concluded with a television film, Ed, Edd n Eddy's Big Picture Show, on November 8, 2009.

Ed, Edd n Eddy received critical acclaim and became one of Cartoon Network's most successful original series. It won a Reuben Award, two Leo Awards and a SOCAN Award, and was also nominated for another four Leo Awards, an Annie Award and two Kids' Choice Awards. The show attracted an audience of 31 million households, was broadcast in 120 countries, and proved to be popular among children, teenagers, and adults. The series has also included spin-off media such as video games, DVD releases, and a series of books and comic books featuring characters from the series. With over a 10-year run, Ed, Edd n Eddy would become the longest running singular Cartoon Network original series. The series also was broadcast on Teletoon in Canada.
