The SAR supergroup is a clade that includes Stramenopiles (aka Heterokonts), Alveolates, and Rhizaria.[1][2][3][4]

The first letter of each group provides the "SAR" in the name.

It includes most of the organisms in the Chromalveolata grouping, but not Hacrobia.

The term "Harosa" (at the subkingdom level) has also been used for this grouping.[5]
