Pentanema britannica, the British yellowhead or meadow fleabane, is a Eurasian species of plant in the daisy family. It is widespread across much of Europe and Asia, and sparingly naturalized in scattered locations in North America.

Pentanema britannica is an erect herb up to 75 cm (30 inches) tall, with fine hairs but not the thick woolly coat characterizing some related species. Leaves are lance-shaped, up to 5 cm (2 inches) long. One plant produces a few heads, each on a long flower stalk. Each had contains 50-150 yellow ray flowers and 100-250 yellow disc flowers.

The plant produces the flavonol axillarin.
