The Andean catfish (Astroblepus ubidiai) is a species of freshwater fish in the family Astroblepidae.

It is endemic to the highlands of the Ecuadorian Andes where it lives in mountain streams in four different drainage basins in the Imbakucha watershed.

The Andean catfish's natural habitats are the mountainous rivers, freshwater springs or aquifers, caves and inland karsts of four different drainage basins within the Imbakucha watershed.

Like all other catfishes, it has barbels around the mouth which contain taste buds that help the animal find food at night.

Habitat loss has fragmented its population; natural and anthropogenic barriers, such as pasture grounds, fields, human settlements, and the presence of predators such as piscivorous large mouth bass in Imbakucha Lake have resulted in the segregation of its six subpopulations and limit their probabilities of escape to other refugia when the environment deteriorates.
