Marmot, a stout-bodied, short-legged burrowing rodent of Europe, Asia, and North America. An adult marmot is about two feet (60 cm) long. It has long, coarse fur, usually brown on the upper side; small ears; and a short, bushy tail. Marmots hibernate during winter. They feed chiefly on vegetation. The European marmot lives high in the Alps, Carpathians, and Pyrenees. American species include the hoary marmots and yellow-bellied marmots of the western United States and Canada, and the wood-chuck.

The European marmot is Marmota marmota; hoary, M. caligata; yellow-bellied, M. flaviventris. Marmots belong to the squirrel family, Sciuridae.
