Paramylodon is an extinct genus of ground sloth of the family Mylodontidae endemic to North America during the Pliocene through Pleistocene epochs, living from around 4.9 million years ago to 11,000 years ago. These animals weighed up to 2400 pounds and were 10 feet long.

Paramylodon is known from North America deposits as far south as Guatemala as well as Mexico and the United States and often mistaken as Glossotherium. Currently there is just one recognized species, P. harlani, that is commonly referred to as Harlan's ground sloth in honor of American paleontologist Dr. Richard Harlan who first discovered and described a lower jaw in 1835. Paramylodon exhibits the interesting characteristic of having had dermal ossicles, small bones embedded in the skin, presumably adding a degree of protection to the animal.
