Cirsium palustre (the Marsh thistle or European swamp thistle) is a herbaceous biennial species of the genus Cirsium.[1] It is a tall thistle that reaches up to 2 metres in height. The strong stems have few branches and are covered in small spines. The spiky leaves are narrow and lobed. The purple flowers are produced in the northern hemisphere from June to September and are 10-20 millimetres across with purple-tipped bracts. It is native to Europe where it is particularly common on damp ground such as marshes, wet fields, moorland and beside streams. In North America it is an introduced species that has become invasive.

C. palustre is broadly distributed throughout northern Europe and eastward to central Asia. According to C. Michael Hogan, this thistle's occurrence is linked to the evolution of human agriculture since at least the mid-Holocene era.[2] It is a dominant plant of several fen-meadow plant associations, including the Juncus subnodulosus-Cirsium palustre fen-meadow.[2]
