Salvia aethiopis is a species of perennial plant known by the common names Mediterranean sage or African sage. It is best known as a noxious weed, particularly in the western United States. It is native to Eurasia and was probably introduced to North America as a contaminant of alfalfa seed. It is a weed of rangelands and pastures. It is unpalatable to livestock, it disrupts native floral communities, and it becomes a physical nuisance due to its habit of becoming an abundant tumbleweed. The weevil Phrydiuchus tau is used as an agent of biological pest control on this plant.
