Marshallia grandiflora, the Monongahela Barbara's buttons, is a species of flowering plant in the genus Marshallia within the sunflower family. It is endemic to the central Appalachia region in the Eastern United States from southwestern Pennsylvania to eastern Tennessee.
It is found primarily along gravelly and sandy bars along high-gradient rivers. Due to this restricted habitat, it is considered globally rare. The largest population occurs along the Gauley River in West Virginia.
Marshallia grandiflora is an herb up to 90 cm (3 feet) tall. Most of the leaves are clustered around the base of the stem. One plant will produce one or two heads, each head containing pink disc flowers but no ray flowers.
