The Scott Bar salamander (Plethodon asupak) is a species of salamander in the family Plethodontidae, endemic to the United States, where it is restricted to a very small range in the Scott River drainage in Siskiyou County, California, at altitudes between 700 and 1,300 metres (2,300 and 4,300 ft) above sea level.

It has a broad brown or bronze dorsal stripe and is otherwise purplish-gray with white flecks that condense on the sides and limbs into larger patches.

[2][4] A species endemic to California,[3] it inhabits shaded, moss-covered talus slopes in old-growth mixed evergreen and montane fir forests of the Klamath Mountain Range.

[1] With a very restricted range and a habitat requirement for old-growth forest, this salamander is threatened by logging which is allowed, under certain circumstances, inside the national forest it inhabits.

The International Union for Conservation of Nature has assessed it as being an endangered species.
