Cornus piggae is an extinct species of dogwood known from fossil fruits found in Late Paleocene sediments exposed in the US state of North Dakota. C. piggae is one of three extinct species placed in the Cornus subgenus Cornus based on fossil fruit morphology. The other two species, C. ettingshausenii and C. multilocularis are known from pyritized fruits found in sediments of the London Clay in England. C. piggae is the only North American fruit species yet described and is also the oldest described species in Cornus subgenus Cornus.
