The Andean potoo has been recorded at approximately a dozen sites along the Andes mountain chain, ranging from western Venezuela through Colombia, Ecuador, and Peru to western Bolivia.
Distribution Explanations
This patchy known distribution could either reflect that the species is truly restricted to local areas, or result from challenges detecting it: it has cryptic camouflage, is nocturnal, and occurs in areas with few resident ornithologists.

Most individuals are found at elevations between roughly 1,800 and 2,800 m (5,900 and 9,200 ft).
Elevation Extremes
The lowest documented elevation for the species is 1,400 m (4,600 ft), and the highest is 3,200 m (10,500 ft).
Habitat
It lives in the canopy of both the interior and edges of humid montane forest.
