Arctostaphylos (/ˌɑːrktoʊˈstæfɪləs, -lɒs/;[1][2] from ἄρκτος árktos "bear" and σταφυλή staphulḗ "bunch of grapes") is a genus of plants comprising the manzanitas (/ˌmænzəˈniːtəz/[3][4]) and bearberries.

There are about 60 species of Arctostaphylos, ranging from ground-hugging arctic, coastal, and mountain shrub to small trees up to 6 m (20 ft) tall.

Most are evergreen (one species deciduous), with small oval leaves 1–7 cm (0.4–3 in) long, arranged spirally on the stems.

One species, however, A. uva-ursi (common bearberry), is adapted to arctic and subarctic climates and has a circumpolar distribution in northern North America, Asia and Europe.

An unusual association of manzanita occurs on Hood Mountain, in Sonoma County, California, where stands of pygmy forest dominated by Mendocino cypress are found.
