The pale lilliput naiad, pale lilliput pearly mussel, or pale lilliput, scientific name Toxolasma cylindrellus, is a species of freshwater mussel, an aquatic bivalve mollusk in the family Unionidae, the river mussels.


This species is endemic to the United States. It has experienced a great range reduction and is currently found only in the Paint Rock River drainage in northern Alabama and southeastern Tennessee. The most recent surveys failed to find this species in the Tennessee portion of the drainage.
