Larinus planus is an insect of the Curculionidae family. They are oval shaped, dark brown or black, and about 5–10 millimetres long. While native to Europe, it is also common in North America. It feeds on floral buds, primarily of thistles, with the larvae stage being the most destructive to them. In North America, it has been used as a biocontrol agent. It is also known as Larinus carlinae.
