Tres Alamos is a ghost town in Cochise County in the U.S. state of Arizona. The town was settled in 1874 in what was then the Arizona Territory.
In 1768 Spanish soldiers from the Presidio de Tucson farmed the area along the San Pedro River to supply food for the Presidio. Later, in 1830, Mexican farmers settled in the area, establishing more permanent farming operations and transporting their produce through the Redington Pass to Tucson with the protection of soldiers from the Presidio.
The Tres Alamos post office was established in 1874 to serve ranchers along the San Pedro River. The post office was eventually closed in 1886. All of the valley settlements and area surrounding them soon became known as Redington.
