Chaenactis macrantha is a species of flowering plant in the daisy family known by the common names bighead dustymaiden and Mojave pincushion. It is native to the Great Basin and the southwestern deserts of the United States, where it grows in dry, open habitat with gravelly, sandy soils, often calcareous or alkaline in nature. It is an annual herb growing one or more branching stems to 30 or 35 centimeters in maximum height. The leaves are a few centimeters long and divided into many lobes. The inflorescence bears one or more flower heads on long peduncles. The flower head is lined with woolly phyllaries which have recurved tips.
