Miss Julie
The tragic protagonist of the play and the twenty-five-year-old daughter of the Count who owns the estate in which it is set. Miss Julie is headstrong and imperious as a result of her mother raising her to adopt the cultural position of a man. These aspects of her personality lead to the breaking off of her former engagement and resulting "wild" behavior. Her character is of a dual nature, switching between social superiority and dalliance with her more common associates, desiring dominion over men but also indulging in weakness and cravenness.
Jean
The thirty-year-old valet of the Count's estate. He is the subject of Miss Julie's advances after her failed engagement. Jean suffers from a profound envy regarding his position in the class system, and as a result, he has a great capacity for cruelty. While initially presenting himself as courteous, he soon reveals his inner sadism. Like Miss Julie, he is of a somewhat dual nature and simultaneously degrades her while envying her social position.
Kristin
The thirty-five-year-old cook at the Count's estate, and Jean's apparent fiancé. She shares in Jean's gossip about Miss Julie's scandalous behavior. She is extremely religious and an ardent believer in the class system, offering a stark contrast to the views of Jean.
The Count
Miss Julie's father and the head of the household. Although he never appears onstage himself, he has a strong presence through his large boots and the sound of the bell at his return. He has a large impact on the events of the play despite not appearing physically, as he embodies the class structure and the patriarchal system.
