Surveys for freshwater oligochaetes (Annelida, Clitellata) conducted during the years 1999–2006 increase to 19 the number of species (representing four families and 13 genera) recorded from Great Smoky Mountains National Park (GSMNP) in North Carolina and Tennessee. Three of these species—Pristina aequiseta, Pristina osborni, and Spirosperma ferox—are new state records for Tennessee, and all but one represent new records for GSMNP. Prior to this study, only one freshwater oligochaete, Stylodrilus wahkeenensis, had been reported from GSMNP.
