Whaling in the Faroe Islands takes the form of beaching and slaughtering long-finned pilot whales, a type of dolphin drive hunting. It has been practised since about the time of the first Norse settlements on these North Atlantic islands and thus can be considered aboriginal whaling. It is mentioned in the Sheep Letter, a Faroese law from 1298, a supplement to the Norwegian Gulating law It is regulated by the Faroese authorities. Around 800 long-finned pilot whales and some Atlantic white-sided dolphins are slaughtered annually, mainly during the summer.
