Blubber is a thick layer of insulating fat found under the skin of cetaceans and various other animals living in extremely cold climates (seals, walruses).

Blubber forms an important part of the traditional eskimo diet because of its high energy value. One of the major reasons for the whaling trade was the collection of whale blubber. This was rendered down into oil in giant cauldrons or later, in vats on factory ships.
