Ranunculus arvensis, the corn buttercup or field buttercup, is a plant species in the family Ranunculaceae. Native to Europe, it can be found on other continents as an introduced species and sometimes a weed, including in North America and Australia. It was formerly a common annual arable weed in Britain, but is now rare there. It is most often found in moist places, such as spring puddles in meadows.
