Jack Reacher is a fictional protagonist of a series of novels, novellas and short stories by British author Jim Grant under the pen name Lee Child. A former major in the United States Army Military Police Corps, Reacher roams the United States taking odd jobs and investigating suspicious and frequently dangerous situations. The Reacher novels are written either in the first person or third person. The schedule for the Reacher series is one per year, except for 2010, when two were published. Most of the novels are set in the United States, in locales ranging from major metropolitan areas like New York City and Los Angeles to small towns in the Midwestern United States and the Southern United States. To date, Reacher's travels outside the United States have taken him to rural England (The Hard Way, Maybe They Have a Tradition), London (Personal), Hamburg (Night School) and Paris (The Enemy, Personal).
The character has been portrayed by Tom Cruise in a 2012 film and 2016 sequel and Alan Ritchson in a streaming television series that premiered on Amazon Prime Video in 2022.
