Sorbus aucuparia, commonly called rowan and mountain-ash, is a species of deciduous tree or shrub in the rose family. It is a highly variable species, and botanists have used different definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan.

S. aucuparia has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. The plant is undemanding and frost hardy and colonizes disrupted and inaccessible places as a short-lived pioneer species.

Fruit and foliage of S. aucuparia have been used by humans in the creation of dishes and beverages, as a folk medicine, and as fodder for livestock. Its tough and flexible wood has traditionally been used for woodworking. It is planted to fortify soil in mountain regions or as an ornamental tree and has several cultivars.

The binomial name Sorbus aucuparia is composed of the Latin words sorbus for service tree and aucuparia, which derives from the words avis for "bird" and capere for "catching" and describes the use of the fruit of S. aucuparia as bait for fowling. The plant is commonly known as rowan and mountain-ash, and has also been called Amur mountain-ash, European mountain-ash, quick beam, quickbeam, or rowan-berry. The names rowan and mountain ash may be applied to other species in Sorbus subgenus Sorbus, and mountain ash may be used for several . The species is unrelated to the true ash trees (genus Fraxinus), which also carry pinnate leaves or the species Eucalyptus regnans, also called mountain ash, native to Tasmania and Victoria in southeastern Australia.S. aucuparia was previously categorized as Pyrus aucuparia. The author citation Sorbus aucuparia L. belongs to Carl Linnaeus.
