Plestiodon gilberti, commonly known as Gilbert's skink, is a species of heavy-bodied medium-sized lizard in the family Scincidae.

The species is endemic to the southwestern United States and northwestern Mexico, and grows to about 7 to 12 cm (3 to 4.5 in) in total length (including tail).

Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Plestiodon.

It is found in the northern San Joaquin Valley, in the foothills of the Sierra Nevada from Butte County southward, and along the inner flanks of the Coast Ranges from San Francisco Bay to the Mexican border and into northern Baja California.

Spotted in Kern County, west of the Rand Mountains bordering San Bernardino, but greater numbers were found east, dispersed north of the Mojave Desert.

Adult females construct nest chambers in loose moist soil several centimeters deep, especially under flat stones.
