The Miller Lake lamprey (Entosphenus minimus) is a species of lamprey in the Petromyzontidae family endemic to the United States. Its natural habitat is the Miller Lake drainage in the state of Oregon. This species is of special interest because it has an extremely limited distribution, with all known animals contained within a single small drainage system, and it is the smallest known parasitic lamprey in the world.
