A comic book convention or comic con is a fan convention with a primary focus on comic books and comic book culture, in which comic book fans gather to meet creators, experts, and each other. Commonly, comic conventions are multi-day events hosted at convention centers, hotels, or college campuses. They feature a wide variety of activities and panels, with a larger number of attendees participating in cosplay than most other types of fan conventions. Comic book conventions are also used as a vehicle for industry, in which publishers, distributors, and retailers represent their comic-related releases. Comic book conventions may be considered derivatives of science-fiction conventions, which began in the late 1930s.

A comic book, also called comicbook, comic magazine or simply comic, is a publication that consists of comics art in the form of sequential juxtaposed panels that represent individual scenes. Panels are often accompanied by descriptive prose and written narrative, usually, dialogue contained in word balloons emblematic of the comics art form.
