Mammillaria plumosa, the feather cactus, is a species of flowering plant in the family Cactaceae, native to Northeastern Mexico.

The spines are adorned with very long hairs that are arranged like the segments of a bird's feather and protect the plant against the blistering sun of the desert. White or greenish yellow flowers are borne in late summer. ^[2]

Its status is listed as "Near Threatened" by the IUCN Red List. ^[1]
