Phaq'u Q'awa is a 5,203-metre-high (17,070 ft) mountain in the Cordillera Occidental in the Andes of Bolivia.

Phaq'u Q'awa lies southeast of Wila Qullu.

The river Phaq'u Q'awa (Pacocahua) originates southwest of the mountain.

It flows to the north as a right tributary of the Lauca River.

[1][2] Phaq'u Q'awa derives from Aymara language terms phaq'u, paqu, or p'aqu meaning the color light brown, reddish, fair-haired, or dark chestnut, and q'awa meaning little river, ditch, crevice, fissure, or gap in the earth,[3][4] the name thus meaning "brown brook" or "brown ravine".
