Wild boar (Sus scrofa), also known as wild pig, is a species of the pig genus Sus, part of the biological family Suidae. The species includes many subspecies. It is the wild ancestor of the domestic pig, an animal with which it freely hybridises. Wild boar are native across much of Northern and Central Europe, the Mediterranean Region (including North Africa's Atlas Mountains) and much of Asia as far south as Indonesia. Populations have also been artificially introduced in some parts of the world, most notably the Americas and Australasia, principally for hunting. Elsewhere, populations have also become established after escapes of wild boar from captivity. The term boar is used to denote an adult male of certain species including, confusingly, domestic pigs. However, for wild boar, it applies to the whole species, including, for example, 'wild boar sow' or 'wild boar piglet'. Wild boar are also known by various names, including wild hogs or simply boars.
