James Hopper Jr. is a fictional character from the Netflix science fiction horror television series Stranger Things, portrayed by David Harbour. He is a Vietnam veteran and the alcoholic chief of police in the small town of Hawkins, Indiana, who, throughout the first three seasons, investigates the strange occurrences in the town. Initially fairly reclusive and lonely due to the death of his daughter, Hopper gradually grows out of his shell, becoming the adoptive father of Eleven, and later starting a relationship with Joyce Byers.
