= alternative and valid name) are a family of plants including 13 genera and ca 750 species.

They are mostly trees and shrubs,[4] with milky sap and fruits or capsules for seeds.

One feature which is sometimes found in this family, and rarely in others (e.g., Malpighiaceae), is providing pollinators with "pollination rewards" other than pollen or nectar; specifically, some species offer resin, which certain bees use in nest construction (each Clusiaceae species offers only one type of reward).

Elements of the Hypericoideae are more common in northern temperate areas and those of the Clusioideae are centered in the tropics.

Their inclusions make the Clusiaceae in a wide sense polyphyletic, and Stevens's subfamilies need to be recognised at family level: Clusioideae as Clusiaceae sensu stricto; Hypericoideae as Hypericaceae; and Kielmeyeroideae as Calophyllaceae.
