The spectacled bear, also known as the Andean bear or Andean short-faced bear and locally as jukumari (Aymara), ukumari (Quechua) or ukuku, is the last remaining short-faced bear. Overall, its fur is blackish in color, though bears may vary from jet black to dark brown and to even a reddish hue. Males can weigh from 100 to 200 kg (220 to 440 lb), and females can weigh from 35 to 82 kg (77 to 181 lb). Head-and-body length can range from 120 to 200 cm (47 to 78.5 in).

Spectacled bears are mostly restricted to certain areas of northern and western South America. They can range in western Venezuela, Colombia, Ecuador, Peru, western Bolivia, and northwestern Argentina. The children's character Paddington Bear is a spectacled bear, famously from "darkest Peru".
