Rhadine caudata is a species of beetle native to the eastern United States. It is a brachypterous (incapable of flight) habitat specialist, occurring in only two of five forest classes in a North Carolina study. R. caudata is a considered a Vulnerable species at the global level on NatureServe, Imperiled in Alabama, and Vulnerable in Virginia.

R. caudata occurs in both surface and subsurface environments, studying it and other species in the genus Rhadine may reveal more about the evolution of subterranean life, regressive evolution, and biodiversity indicators.

It was first formally named by John Lawrence LeConte in 1863 as Platynus caudatus and later transferred to the genus Rhadine.
