The St. Kitts bullfinch (Melopyrrha grandis), known locally as the mountain blacksmith, is a presumably extinct songbird species of the genus Melopyrrha which was endemic to the island of Saint Kitts. It was previously considered conspecific with the Puerto Rican bullfinch (Melopyrrha portoricensis), from which it could be distinguished by its larger size, glossier feathers, and more extensive breast patch.
