Cochise County is a county in the southeastern corner of the U.S. state of Arizona. It is named after the Native American chief Cochise.

The population was 131,346 at the 2010 census. The county seat is Bisbee and the most populous city is Sierra Vista.

Cochise County includes the Sierra Vista-Douglas, Arizona Metropolitan Statistical Area. The county borders southwestern New Mexico and the northwestern Mexican state of Sonora.


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.

J.A. Jance's Joanna Brady mystery series takes place in Cochise County, with Brady being the sheriff.

Beginning in the late 1950s, the small community of Miracle Valley was the site of a series of bible colleges and similar religious organizations, founded by television evangelist A. A. Allen. In 1982, Miracle Valley and neighboring Palominas were the site of a series of escalating conflicts between a newly arrived religious community and the county sheriff and deputies that culminated in the Miracle Valley shootout.


According to the U.S. Census Bureau, the county has a total area of 6,219 square miles (16,110 km2), of which 6,166 square miles (15,970 km2) is land and 53 square miles (140 km2) (0.9%) is water. Cochise County is close to the size of the States of Rhode Island and Connecticut combined.
