A character (sometimes known as a fictional character) is a person or other being in a narrative work of art (such as a novel, play, television series, or film). The character may be entirely fictional or based on a real-life person, in which case the distinction of a "fictional" versus "real" character may be made. Derived from the ancient Greek word χαρακτήρ, the English word dates from the Restoration, although it became widely used after its appearance in Tom Jones in 1749. From this, the sense of "a part played by an actor" developed. Character, particularly when enacted by an actor in the theatre or cinema, involves "the illusion of being a human person." In literature, characters guide readers through their stories, helping them to understand plots and ponder themes. Since the end of the 18th century, the phrase "in character" has been used to describe an effective impersonation by an actor. Since the 19th century, the art of creating characters, as practiced by actors or writers, has been called characterisation.

A character who stands as a representative of a particular class or group of people is known as a type. Types include both and those that are more fully individualised. The characters in Henrik Ibsen's Hedda Gabler (1891) and August Strindberg's Miss Julie (1888), for example, are representative of specific positions in the social relations of class and gender, such that the conflicts between the characters reveal ideological conflicts.
