Hieracium laevigatum, or smooth hawkweed, is a Eurasian plant species in the tribe Cichorieae within the family Asteraceae. It is widespread across much of Europe and western Asia.^[2] It is very similar to Hieracium sabaudum and can be found on dry, more or less nutrient rich soil in light woods, grassy embankments and fields, or on walls.^[3]

Hieracium laevigatum is an herb up to 60 cm (2 feet) tall, with leaves on the stem rather than in a rosette at the bottom. Leaves are lance-shaped, up to 10 cm (4 inches) long, with large teeth along the edge. One stalk branches toward the top, producing numerous flower heads. Each head has several ray flowers but no disc flowers.^[4]
