|Vaccinium berries, from top left clockwise:
Red huckleberries, cranberries, lingonberries and blueberries
Vaccinium (pron.: //) is a genus of shrubs or dwarf shrubs in the plant Family Ericaceae. The fruit of many species are eaten by humans and some are of commercial importance, including the cranberry, blueberry, bilberry or whortleberry, lingonberry or cowberry, and huckleberry. Like many other ericaceous plants, they are generally restricted to acidic soils.
The genus contains about 450 species, which are found mostly in the cooler areas of the Northern Hemisphere, although there are tropical species from areas as widely separated as Madagascar and Hawaii.
The name vaccinium was used in classical Latin for a type of berry (probably the bilberry V. myrtillus), but its ultimate derivation is obscure; it is not the same word as vaccinum "of or pertaining to cows".
Plants of this group typically require acidic soils, and as wild plants they live in habitats such as heath, bog and acidic woodland (for example, blueberries under oaks or pines). The plant structure varies between species – some trail along the ground, some are dwarf shrubs, and some are larger shrubs perhaps 1 to 2 m (3 to 7 ft) tall. The fruit develops from an inferior ovary, and is a berry; it is usually brightly coloured, often being red or bluish with purple juice.
The metabolism and photosynthetic parameters of Vaccinium can also slightly alter in winter-warming experiments.
Food uses 
The taxonomy is complex, and still under investigation. A number of the Asian species are more closely related to Agapetes than to other Vaccinium species. A second group includes most of Orthaea and Notopora, at least some of Gaylussacia (huckleberry), and a number of species from Vaccinium, such as Vaccinium crassifolium. Other parts of Vaccinium form other groups, sometimes together with species of other genera.
A classification predating molecular phylogeny divides Vaccinium into subgenera, and several sections:

- Subgenus Vaccinium
- All the other species, with thicker, upright woody shoots and bell-shaped flowers.
