Blue (originally, Whittum) is an unincorporated community in Greenlee County, Arizona, United States.
Blue has a ZIP Code of 85922; in 2000, the population of the 85922 ZCTA was 36.[1] In addition to its post office, Blue also contains a public library, and a public school serving all grade levels.
The community was originally named for Nat Whittum, an original settler who was killed at the site in 1891. A post office was established at Whittum in 1894; however, its name was changed to Blue in 1898.
Blue's population was 80 in the 1940s.[2]
Blue School District 22 is the area school district, serving K-12. In 1984 Randy Collier of The Arizona Republic stated due to difficulties in transportation and from being far from other places, "the social life at Blue primarily is at the school."[3]
Previously Blue had a K-8 school, so Round Valley High School in Eagar, of the Round Valley Unified School District, served Blue for high school; some students lived with relatives in Eagar and some traveled to and from Eagar via school bus.[4]
Greenlee County Library System maintains the Blue Public Library in a log cabin adjacent to the Blue School.[5]
