The Canelo Hills are a range of low mountains or hills in eastern Santa Cruz County, Arizona. The range consists of a series of northwest–southeast trending ridges extending from the Sonoita Creek valley southwest of Sonoita to the Parker Canyon Lake area in southwest Cochise County, Arizona. The Canelo Hills merge with the Huachuca Mountains to the southeast. The San Rafael Valley lies to the southwest of the range and the Patagonia Mountains lie to the west across the Harshaw Creek valley.
