Magharet el Kantara or Shaw's Cave (Arabic: مغارة القنطرة, arched cave) is a rock art shelter of the Gilf Kebir National Park in the New Valley Governorate, Egypt.

Located on the south-western slopes of Gilf Kebir, it was discovered in 1935 by the explorers Bill Kennedy Shaw and Rupert Harding Newman.

[1] The cave is 4 m (13 ft) high and 15 m (49 ft) wide.

About half a meter above the ground there are rock paintings of a herd of differently drawn cattle and a farmstead representing a rare example of cattle paintings in the Gilf Kebir that otherwise are abundant in the nearby Jebel Ouenat.

[2] These Neolithic rock paintings testify the favorable climatic conditions of life during the African humid period much different from the present one.
