槲寄生属（学名：Viscum）是桑寄生科下的一个属，为寄生灌木植物。该属共有约30种，分布于东半球热带至温带。

Viscum is a genus of about 70–100 species of mistletoes, native to temperate and tropical regions of Europe, Africa, Asia and Australasia. Traditionally, the genus has been placed in its own family Viscaceae, but recent genetic research by the Angiosperm Phylogeny Group shows this family to be correctly placed within a larger circumscription of the sandalwood family, Santalaceae.
