Cochise County is a county located in the southeastern corner of the U.S. state of Arizona. The population was 131,346 at the 2010 census. The county seat is Bisbee.

Cochise County comprises the Sierra Vista-Douglas, AZ Metropolitan Statistical Area. The county borders southwestern New Mexico and northwestern Sonora in Mexico.

Cochise County was created on February 1, 1881, out of the eastern portion of Pima County. It took its name from the legendary Chiricahua Apache war chief Cochise. The county seat was Tombstone until 1929 when it moved to Bisbee. Notable men who once held the position of County Sheriff were Johnny Behan, who served as the first sheriff of the new county, and who was one of the main characters during the events leading to and following the Gunfight at the O.K. Corral. Later, in 1886, Texas John Slaughter became sheriff. Lawman Jeff Milton and lawman/outlaw Burt Alvord both served as deputies under Slaughter.

A syndicated television series which aired from 1956 to 1958, Sheriff of Cochise starring John Bromfield, was filmed in Bisbee. The Jimmy Stewart movie Broken Arrow and subsequent television show of the same name starring John Lupton, which also aired from 1956 to 1958, took place (but was not filmed) in Cochise County.
