Icelandic cuisine, the cuisine of Iceland, has a long history. Important parts of Icelandic cuisine are lamb, dairy, and fish, the latter due to the fact that Iceland has traditionally been inhabited only near its coastline. Popular foods in Iceland include skyr, hangikjöt, kleinur, laufabrauð, and bollur. Þorramatur is a traditional buffet served at midwinter festivals called Þorrablót; it includes a selection of traditionally cured meat and fish products served with rúgbrauð and brennivín. The flavors of this traditional country food originate in its preservation methods; pickling in fermented whey or brine, drying, and smoking.

Whale meat, broadly speaking, may include all cetaceans and all parts of the animal: muscle (meat), organs (offal), skin (muktuk), and fat (blubber). There is relatively little demand for whale meat, compared to farmed livestock. Commercial whaling, which has faced opposition for decades, continues today in very few countries, despite whale meat being eaten across Western Europe and colonial America previously. However, in areas where dolphin drive hunting and aboriginal whaling exist, marine mammals are eaten locally as part of a subsistence economy: the Faroe Islands, the circumpolar Arctic, other indigenous peoples of the United States, St. Vincent and the Grenadines, some of villages in Indonesia and in certain South Pacific islands.
