Prunus emarginata, the bitter cherry or Oregon cherry, is a species of Prunus native to western North America, from British Columbia south to Baja California, and east as far as western Wyoming and New Mexico. It is often found in recently disturbed areas or open woods on nutrient-rich soil.

Prunus emarginata is a deciduous shrub or small tree growing to 1-15 metres (3.3-49.2ft) tall with a slender oval trunk with smooth gray to reddish-brown bark with horizontal lenticels. The leaves are 2-8 centimetres (0.79-3.15in) long, thin, egg-shaped, and yellowish-green with unevenly sized teeth on either side. The flowers are small, 10-15mm diameter, with five white petals and numerous hairlike stamens; they are almond-scented, and produced in clusters in spring, and are pollinated by insects. The fruit is a juicy red or purple cherry 7-14mm diameter, which, as the plant's English name suggests, are bitter. As well as reproducing by seed, it also sends out underground stems which then sprout above the surface to create a thicket.
There are two varieties:
It has hybridized with the introduced European Prunus avium in the Puget Sound area; the hybrid has been named as Prunus pugetensis. It is intermediate between the parent species, but is nearly sterile, producing almost no cherries.
The cherries are not very palatable and have been known to cause illness in humans, but animals, especially birds, forage on them.
Native tribes, most notably Kwakwaka'wakw, used other parts of the plant for medicinal purposes, such as poultices and bark infusions. The isoflavone prunetin was isolated for the first time by Finnemore in 1910 from the bark of P. emarginata.
