油杉寄生属（学名：Arceuthobium）是桑寄生科下的一个属，为矮小草本或亚灌木植物。该属共有30种，分布于北半球温带至亚热带。

The genus Arceuthobium, commonly called dwarf mistletoes, is a genus of 42 species of parasitic plants that parasitize members of Pinaceae and Cupressaceae in North America, Central America, Asia, Europe, and Africa. Of the 42 species, 39 and 21 are endemic to North America and the United States, respectively. They all have very reduced shoots and leaves (mostly reduced to scales) with the bulk of the plant living under the host's bark. Recently the number of species within the genus has been reduced to 26 as a result of more detailed genetic analysis.
