The Guadalupe Mountains of Hidalgo County (Spanish: Sierra de Guadalupe) are a 13 mi (21 km) long, sub-range in southwest Hidalgo County, New Mexico, United States, adjacent to the southeast border of Arizona's Cochise County. A small portion of the range is in Cochise County, namely the outlet of Guadalupe Canyon, famous for the Guadalupe Canyon Massacre. The southernmost end of the range is also in the border region of Sonora, just north of Federal Highway 2.
The Guadalupe Mountains are on the southern end of the extensive north–south Peloncillo Mountains, that abut the Arizona border.
