The Del Norte salamander (Plethodon elongatus) is a species of salamander in the family Plethodontidae endemic to the United States in southwestern Oregon and northwestern California.

No free-living larval stage exists, and juveniles hatch completely metamorphosed, measuring about 18 mm (0.71 in) in snout–vent length.

[3] The species occurs in areas of moist talus and rocky substrates in redwood or Douglas fir forests.

It is typically encountered among moss-covered rocks or under bark and other forest litter, usually avoiding very wet areas.
