The Swisshelm Mountains are a small mountain range adjacent to the southwest corner of the Chiricahua Mountains of eastern Cochise County, Arizona. They are separated from the Pedrogosa Mountains to the southeast, the Chiricahua's to the northeast, and by Leslie Creek, bordering the south and east; the area is now notable for the Leslie Canyon National Wildlife Refuge. The mountain range is named for John Swisshelm, a miner, a local settler of the late 1900s.
