List of Yucca species

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.

As of 2025 Plants of the World Online (POWO) and World Flora Online both list 50 valid species. In addition, POWO lists three other species, Yucca jaegeriana (McKelvey) L.W.Lenz, Yucca muscipula Ayala-Hern., Ríos-Gómez, E.Solano & García-Mend., and Yucca pinicola Zamudio, 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.
