Prunus subg. Padus (bird cherries) is a subgenus of Prunus, characterised by having deciduous leaves, flowers 12-30 together on slender racemes produced in late spring well after leaf emergence, and small, sour fruit usually only palatable to birds, hence the name. They are native throughout the temperate Northern Hemisphere.

Bird cherries are sometimes used as a food plant by Lepidoptera species including brimstone moth.

Some bird cherries, such as chokecherries, are used to make jelly and wine in North America.

Some botanists treat the subgenus as a distinct genus Padus.
