欧楂（学名：Mespilus germanica）是原产于亚洲西南部和在欧洲东南部的落叶植物，1930年代引种到中国青岛，常被栽培作为果树。 　　

它被广泛种植于欧洲和美国境内。 树高15至20英尺（4.5至6米），可通过播种或者嫁接繁殖。叶似鱼叉，略长带绒，开有1.5英寸（4厘米）白色或粉色的花。果实形似苹果，称亦欧楂果，直径约 1.5至2英寸（4至5厘米），味道略酸，成熟于深秋。冷霜可使果子变软，称此过程为软化（bletting）。欧楂果主要用来做成果酱而食，但也可新鲜食用。

Mespilus germanica, known as the medlar or common medlar, is a large shrub or small tree, and the name of the fruit of this tree. The fruit has been cultivated since Roman times, and is unusual in being available in winter, and in being eaten when bletted. It is eaten raw and in a range of dishes. When the genus Mespilus is included in the genus Crataegus, the correct name for this species is Crataegus germanica Kuntze.
