榅桲（音wēn•po，学名：Cydonia oblonga，英语：Quince），又名木梨，是榅桲属中唯一物种。

落叶小乔木或灌木，一般为5-8米高；卵形或长椭圆形叶子，背面密生白色软毛，单叶互生，叶长6-11公厘；晚春或初夏开花，花白色或粉红色，有5瓣，直径约5公厘，花梗和花萼也有毛；果实秋季成熟，梨形或苹果形，未成熟时青色，有白毛，成熟后金黄色，直径有7-11厘米，味甘酸。

原生于中亚和高加索山区；现被引种到世界各地，成为重要的水果品种。

榅桲历史相当悠久，很早就被引进西方，比苹果要更早流行，希腊神话中所传说的“引起纷争的金苹果”，实际是一个金色的榅桲果。榅桲性耐寒，即使在7℃以下也能开花，果实可以生食，也可以制作果酱、蜜饯等食品，也可以酿酒，含有大量维生素C。药用可以治疗肠虚、水泻。中国引种主要生长在西北各地，以**最多。

The quince (/ˈkwɪns/; Cydonia oblonga) is the sole member of the genus Cydonia in the family Rosaceae (which also contains apples and pears, among other fruits). It is a small deciduous tree that bears a pome fruit, similar in appearance to a pear, and bright golden-yellow when mature. Throughout history the cooked fruit has been used as food, but the tree is also grown for its attractive pale pink blossoms and other ornamental qualities.
