The forkshell or Lewis pearly mussel, scientific name Epioblasma lewisii, was a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.
This species was endemic to the drainages of the Cumberland River and the Tennessee River in the United States, with one specimen reported from the Ohio River near Cincinnati, Ohio. Its natural habitat was shallow riffle-beds of large rivers. This habitat was largely destroyed by dam construction and canalization, and the last populations of this species died sometime during the middle of the 20th century. Only a single museum specimen was collected that preserved the internal soft tissues.
