Abo is a pueblo ruin in New Mexico that is preserved in the Salinas Pueblo Missions National Monument.
The Abó Ruins are located about 9 miles west of Mountainair, at about 6100 feet (1859 m) above sea level. They are said to date back to the 1300s. It was a major trading station during its time. There is a visitor contact station, a 0.25 mile (0.4 km) trail through the mission ruins, and a 0.5 mile (0.8 km) trail around the unexcavated pueblo ruins.
It was declared a National Historic Landmark in 1962.
Abo is also the geological type locality for the Abo Formation, which is made up of sandstone red beds and is exposed to the northwest of the Abo ruins.
