History
San Simon was the location of the San Simon Station of the Butterfield Overland Mail on the San Simon River between Apache Pass and Stein's Peak Stations. It was a later relay station established to provide water and change horses on the route.

In September 1880, Southern Pacific's rail line construction from the west reached San Simon and started rail service. Once a junction was made in March 1881 with eastern rails in Deming, New Mexico, the line became the second transcontinental rail route across the United States. San Simon was within Pima County until Cochise County was formed out of the eastern half of Pima in February 1881.
