Cenchrus is a widespread genus of plants in the grass family.[3][6] Its species are native to many countries in Asia, Africa, Australia , the Americas, and various oceanic islands.[7][8]

Common names include buffelgrasses, sandburs, and sand spur. Such names allude to the sharp, spine-covered burrs characterizing the inflorescences of the members of the genus.[9]

Some botanists include the genus within the related genus Pennisetum.
