Parvaspina is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae. It contains only two critically endangered species, both endemic to river basins in a small region of the southeastern United States. ^{[1] [2]}

Species

• Parvaspina collina (James River spinymussel)
• Parvaspina steinstansana (Tar River spinymussel)

Both species in this genus were formerly placed in other genera ( Elliptio for steinstansana, Pleurobema for collina) before both being placed in the new genus Parvaspina in 2017. ^[3]
