Exochorda is a small genus of flowering plants in the family Rosaceae, native to China and central Asia (Turkestan). They are used as ornamental plants with the common name pearl bush, or pearlbush. Numerous species have been described on the basis of differing appearance and geographical separation, but a systematic study revealed that the different types are closely related and probably all descended from a single species that formerly had a wide distribution that has been fragmented by habitat loss. As a single species the correct name is E. racemosa.

The genus was formerly included within the genus Sorbus as the section Torminaria, but the simple-leafed species traditionally classified in Sorbus are now considered to form a separate monophyletic group. It is monotypic, being represented by the single species Torminalis glaberrima, commonly known as wild service tree, chequers, and checker tree. This tree is native to Europe, parts of northern Africa and western Asia.
