Prunus serrulata or Japanese cherry, also called hill cherry, oriental cherry or East Asian cherry, is a species of cherry native to China, Japan, Korea and India, and is used for its spring cherry blossom displays and festivals. Current sources consider it to be part of a species complex with P. jamasakura and P. leveilleana, which have been reduced to synonyms.

Prunus serrulata is a small deciduous tree with a short single trunk, with a dense crown reaching a height of 26–39 feet (7.9–11.9 m). The smooth bark is chestnut-brown, with prominent horizontal lenticels. The leaves are arranged alternately, simple, ovate-lanceolate, 5–13 cm long and 2.5–6.5 cm broad, with a short petiole and a serrate or doubly serrate margin. At the end of autumn, the green leaves turn yellow, red or crimson.
The flowers are produced in racemose clusters of two to five together at nodes on short spurs in spring at the same time as the new leaves appear; they are white to pink, with five petals in the wild type tree. The fruit is a globose black drupe 8–10 mm diameter.
Prunus serrulata is widely grown as a flowering ornamental tree, both in its native countries and throughout the temperate regions of the world. Numerous cultivars have been selected, many of them with double flowers with the stamens replaced by additional petals.
