The area that became the present town of Camargo was part of the Cheyenne and Arapaho Reservation until it was opened for non-Indian settlement on April 19, 1892. A Camargo post office was established on September 16, 1892. A weekly mail route to Camargo from Ioland using the Grand post office was made in 1893.
Two stories exist about the meaning of the town name. One claims that it was named for a town in Illinois, while the other claims Camargo meant "little dog" in the Cheyenne language.
