Padreyoc, Mountain summit in Cordillera Vilcabamba, Peru

Padreyoc, also called Quishuar, is a 5,771-metre mountain in the Vilcabamba range of the Cusco Region, in La Convención Province. It stands south-west of Salcantay and east of Corihuayrachina. Its summit is a jagged crest of snow-covered peaks above dark grey and brown rock faces, with steep shadowed ridges falling away on both sides.

Padreyoc appears in the sources only as a named peak of the Vilcabamba range in La Convención Province, Cusco Region, at 5,771 m; no ascent date or expedition is documented. Its Quechua name Quishuar refers to the kiswar tree (Buddleja incana), a link to the vegetation of the valleys below rather than to any climbing history.

The name Padreyoc mixes Spanish padre (father) with a Quechua suffix -yuq indicating possession. Its other name, Quishuar, comes from Quechua kiswar, the Buddleja incana tree. Both names are still used for the mountain in the Vilcabamba range of La Convención Province.

Padreyoc lies in the Vilcabamba range of La Convención Province, Cusco Region, south-west of Salcantay and east of Corihuayrachina. Approach is from the Cusco side; the nearest town of note is Urubamba, and the peak stands at 5,771 m, so acclimatisation before any attempt is essential. No marked trail or facility is recorded on the mountain itself.

Padreyoc also carries the Quechua name Quishuar, from kiswar, the Buddleja incana tree. The two names sit side by side in the sources: a Spanish-Quechua hybrid meaning "possessor of a father" and a plant name. The peak rises about 5,771 m in the Vilcabamba range, southwest of Salcantay and east of Corihuayrachina, in La Convención Province, Cusco Region.
