梨是梨属（学名：Pyrus）植物的通称，通常是一种落叶乔木或灌木，极少数品种为常绿，属于蔷薇目蔷薇科苹果族。叶片多呈卵形，大小因品种不同而各异。花为白色，或略带黄色、粉红色，有五瓣。果实形状有圆形的，也有基部较细尾部较粗的，即俗称的“梨形”；不同品种的果皮颜色大相径庭，有黄色、绿色、黄中带绿、绿中带黄、黄褐色、绿褐色、红褐色、褐色，个别品种亦有紫红色；野生梨的果径较小，在1到4厘米之间，而人工培植的品种果径可达8厘米，长度可达18厘米。梨的果实通常用来食用，不仅味美汁多，甜中带酸，而且营养丰富，含有多种维生素和纤维素，不同種類的梨味道和質感都完全不同。梨既可生食，也可蒸煮后食用。在医疗功效上，梨可以通便秘，利消化，对心血管也有好处。加熱的梨汁含有大量的抗癌物質多酚，給注射過致癌物質的小白鼠喝這樣的梨汁，白鼠尿液中就能排出大量的1-羥基芘毒素，從而有效預防癌症。除了作为水果食用以外，梨还可以作观赏之用。
