Oligochaeta is a genus of Asian plants in the thistle tribe within the sunflower family.[2][3][4]

Oligochaeta is native to central, southern, and southwestern Asia. They are annual plants that grow in mountain and steppe habitat.[5]

It is part of the Rhaponticum group in the tribe Cynareae, along with the genera Rhaponticum, Acroptilon, Callicephalus, Leuzea, Myopordon, and Ochrocephala.[6] It can be distinguished from other genera by its pollen.[7]
