Longmire is an American neo-Western crime drama television series that premiered on June 3, 2012, on the A&E network, developed by John Coveny and Hunt Baldwin. The series is based on the Walt Longmire Mysteries series of novels by Craig Johnson. It centers on Walt Longmire, a sheriff in Wyoming. He is assisted by staff, friends, and his daughter in investigating major crimes within his jurisdiction.

Longmire became the "highest-rated original drama series" on A&E; however, the network announced in August 2014 that it would not renew the series after the third season. Warner Horizon Television offered it to other networks and Netflix picked it up, starting with season four. Netflix released the sixth and final season on November 17, 2017. It is no longer available for streaming via Netflix in the United States, but is available on a number of other streaming services.
