Pyrus communis, known as the European pear or common pear, is a species of pear native to central and eastern Europe and southwest Asia.

It is one of the most important fruits of temperate regions, being the species from which most orchard pear cultivars grown in Europe, North America, and Australia have been developed. Two other species of pears, the Nashi pear (Pyrus pyrifolia) and the hybrid Chinese white or ya pear (Pyrus × bretschneideri, Chinese:白梨; pinyin:báilí) are more widely grown in East Asia.
