John Reese is a fictional character and the main protagonist of the CBS crime drama television series Person of Interest. Reese is portrayed by actor Jim Caviezel. He works with billionaire Harold Finch to help residents of New York who are potentially involved in violent crime.

Reese is an intense, solitary man whose dry sense of humor emerges over time. He speaks in a low, calm, and confident voice. Extremely skilled with a range of weapons and combat techniques due to his military experience, Reese possesses a level of determination that drives him to work with Finch to protect potential victims of violent crime. Reese owns a dog named Bear, a Belgian Malinois who he rescued from white supremacists and sent to live with Finch to assure Finch's safety.
