Apache Pass, also known by its earlier Spanish name Puerto del Dado, is a historic mountain pass in the U.S. state of Arizona between the Dos Cabezas Mountains and Chiricahua Mountains at an elevation of 5,110 feet (1,560 m). It is approximately 20 miles (32 km) east-southeast of Willcox, Arizona, in Cochise County.

The Chiricahua Mountains massif is a large mountain range in southeastern Arizona which is part of the Basin and Range province of the west and southwestern United States and northwest Mexico; the range is part of the Coronado National Forest. The highest point, Chiricahua Peak, rises 9,759 feet (2,975 m) above sea level, approximately 6,000 feet (1,800 m) above the surrounding valleys. The range takes its name from the Chiricahua Apaches native to the region.
