The Alamo Hueco Mountains are a 15-mile (24 km) long mountain range, located in the southeast of the New Mexico Bootheel region, southeast Hidalgo County, New Mexico, adjacent to the border of Chihuahua state, Mexico. The range lies near the southern end of the mountains bordering the extensive north–south Playas Valley; the Little Hatchet and Big Hatchet Mountains are adjacent, and mostly attached north; the mountain range series, ends south into the flatland plains of the Chihuahuan Desert. The much smaller Dog Mountains are adjacent south.
While the Continental Divide of the Americas traverses the western perimeter mountains of the Playas Valley, the Continental Divide National Scenic Trail traverses the entire mountain ranges on the east side of the Playas Valley; the Scenic Trail continues south into the Chihuahuan Desert region of northwest Chihuahua state.
