The brown-throated sloth (Bradypus variegatus) is a species of three-toed sloth found in the Neotropical realm of Central and South America.

It is the most common of the four species of three-toed sloth, and is found in the forests of South and Central America in countries such as Bolivia, Brazil, Colombia, Ecuador, Honduras, Nicaragua, Panama, Paraguay, Peru, and Venezuela. Although they once lived in Argentina, they are now believed to be extinct there.
