Crupina is a small genus of plants in the tribe Cardueae within the family Asteraceae.

The common crupina Crupina vulgaris is a notorious noxious weed on several continents. The other species, Crupina crupinastrum, also has the potential to become weedy, but it is not as bad a pest at the current time. These are thistle-like plants with bright deep pink flower heads.[http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=108471 Flora of China Vol. 20-21 Page 190 半毛菊属 ban mao ju shu Crupina (Persoon) Candolle][http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=108471 Flora of North America Crupina (Persoon) de Candolle][http://luirig.altervista.org/flora/taxa/floraspecie.php?genere=Crupina Altervista Flora Italiana, genere Crupina]
