Cnidoscolus angustidens, with the common name mala mujer, is an herbaceous perennial plant in the spurge family (Euphorbiaceae).

It is native to the Sonoran Desert mountains of southeastern Arizona and Northwestern Mexico, and further south in Mexico.

"Mala mujer" is Spanish for "bad woman", referring to its stinging hairs which cause severe contact dermatitis.
