This is a list of the species in the genus Yucca. They are commonly called yuccas in English, but are also called Adam's needle or Spanish-bayonet.

Plants of the World Online (POWO) and World Flora Online both list 50 valid species. In addition, POWO lists three other species, Yucca jaegeriana , Yucca muscipula , and Yucca pinicola , that WFO lists as unchecked or as a synonym of another species. There are also two natural hybrids, Yucca × schottii, which was formerly listed as a species under various names, and Yucca × quinnarjenii.
