The Manchurian hare (Lepus mandshuricus) is a species of hare found in northeastern China, the Amur River basin, and in the higher mountains of northern Korea. The adult Manchurian hare weighs about 2 kilograms, and has a body length of 40–48 centimeters (16–19 in), in addition to a tail of 4.5–7.5 centimeters (1.8–3.0 in). The ears are typically 7.5–10.4 centimeters in length. Compared to the Korean hare, its hind legs are relatively short and its ears relatively small. A melanistic morph exists, and has been described as the separate species Lepus melainus.
