Jbel Ayachi (Arabic: جبل العياشي) is one of the highest mountains in North Africa, and anchors the Eastern High Atlas in central Morocco.

Conceptually a ring, the Ayachi region harbors a seasonal lake at its center and is surrounded by peaks and passes that often surpass 3000 m in elevation.

The government of Morocco published accurate topographical maps of the region in 1968, including contours, peaks, and some of the paths and springs.

Nomadic Berbers have inhabited the mountains for many years, raising sheep and goats and remaining largely isolated from the sedentary farmers and market towns of the plains.

The heart of the nomadic community in Ayachi is the village of Tarhirat, which has no permanent dwellings but is centrally located and well-watered.
