Miocnus is an extinct genus of ground sloths of the family Megalocnidae endemic to Cuba during the Pleistocene and very early Holocene epochs, living from 1.8 Mya—11,000 years ago, existing for approximately 1.789 million years.^[2]

Miocnus was named by Matthew (1931). Its type is Miocnus antillensis. It was assigned to Megalonychidae by Matthew (1931) based on morphological considerations,^[3] and subsequently moved to Megalocnidae by Presslee et al. (2019) based on molecular sequence data.^[1]
