Lathyrus pratensis or meadow vetchling, meadow pea and meadow pea-vine, is a perennial legume that grows to 1.2 m in height.

The hermaphrodite flowers are pollinated by bees. As a perennial, this plant reproduces itself over many years, spreading out from the point it was introduced, especially in damp grassy areas. This plant has been propagated in the past as animal fodder.
