Cyclonaias pustulosa, ^[2] the pimpleback, ^[1] is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels. This species is native to North America, where it is widespread ^{[1] [3]} and common. ^[1] It has possibly been extirpated from New York, however, and populations in Pennsylvania are critically imperiled, according to NatureServe. ^[1]

The species was formerly classified within the genus Quadrula , and in 2012 it was moved to Rotundaria based on genetic evidence. ^[4]
