In genre studies, a coming-of-age story is a genre of literature, theatre, film, and video game that focuses on the growth of a protagonist from childhood to adulthood, or "coming of age". Coming-of-age stories tend to emphasize dialogue or internal monologue over action and are often set in the past. The subjects of coming-of-age stories are typically teenagers. The Bildungsroman is a specific subgenre of coming-of-age story.

Coming of age is a young person's transition from being a child to being an adult. The specific age at which this transition takes place varies between societies, as does the nature of the change. It can be a simple legal convention or can be part of a ritual or spiritual event.
