Achyranthes is a genus of medicinal and ornamental plants in the amaranth family, Amaranthaceae. Chaff flower is a common name for plants in this genus. The Hawaiian species (A. divaricata, A. humile, and A. sandwicensis) are known in Hawaiian as kuluī.

A 2024 morphological and phylogenetic analysis by Vanessa Di Vincenzo et al. merged the genus Achyropsis and the Hawaiian genus Nototrichium into Achyranthes to make it monophyletic. The genus is characterized by solitary, fertile flowers.
