Cirsium is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera in having a seed with a pappus of feathered hairs on their achenes. The other genera have a pappus of simple unbranched hairs.
