Rhinostomus is a genus of the true weevil family, Curculionidae and the monotypic tribe Rhinostomini. They include "yucca weevils" and were previously placed in agenus called Yuccaborus; in 2002, this was determined to be a taxonomic synonym of Rhinostomus, and the species, Y. frontalis, was moved to the genus Rhinostomus.
