石楠属（学名：Photinia）包含至少60个种，为蔷薇科苹果亚科的一群小乔木或大型灌木，分布于东南亚和东亚地区，包括中国南部和中部、日本、印度和泰国等地。如果按某些生物学家的观点，将近缘种柳叶石楠（柰石楠，Heteromeles arbutifolia）包含在石楠属中，那幺分布区还要包括北美洲。某些分类法中把红果树（P. davidiana）等部分物种划入红果树属（Stranvaesia），再把部分物种划入Pourthiaea属中。腺肋花楸属（Aronia）在一些分类法中也被包含入石楠属中。其他近缘属包括火棘属（Pyracantha）、栒子属（Cotoneaster）和山楂属（Crataegus）。

Photinia (/foʊˈtɪniə, fə-/) is a genus of about 40–60 species of small trees and large shrubs, but the taxonomy has recently varied greatly, with the genera Heteromeles, Stranvaesia and Aronia sometimes included in Photinia.

They are a part of the rose family (Rosaceae) and related to the apple. The botanical genus name derives from the Greek word photeinos for shiny and refers to the often glossy leaves. Most species are evergreen, but deciduous species also occur. The small apple-shaped fruit has a size of 4 to 12 mm and forms in large quantities. They ripen in the fall and often remain hanging on the bush until well into the winter. The fruits are used as food by birds, which excrete the seeds with their droppings and thereby distribute the plant.
