Pine Valley Mountain Wilderness is a  wilderness area located in the Dixie National Forest in the U.S. state of Utah.  It is the fourth-largest wilderness area located entirely within the state (following the High Uintas Wilderness, Zion Wilderness, and Cedar Mountain Wilderness).  The wilderness designation protects the Pine Valley Mountain range, a large rock outcrop surrounded by desert.  The Pine Valley Mountains form the Pine Valley Laccolith, one of the largest laccoliths in the United States.  Elevations in the wilderness range from  to  at the summit of Signal Peak.

Vegetation

The southern half of the Pine Valley Mountain Wilderness area supports a large stand of virgin Engelmann spruce.  On the south edge of this unit, young stands of bristlecone pine are also found.  The north half of the area is composed of stands of mixed spruce, subalpine fir, Douglas fir, and limber pine.  Stands of large aspen are also found throughout the area.

There are numerous meadows up to  in size within the boundaries of the Wilderness.  The predominant vegetation is mat muhly, subalpine needlegrass, alpine timothy, dandelion, Perry clover, shrubby cinquifoil, yarrow, fleabane, snowberry, and serviceberry.

Wildlife
The Pine Valley Mountains is more or less isolated from the Wasatch Range.  Because of this isolation there are a number of sub-species of mammals found here, including the Uinta chipmunk, yellow-bellied marmot, and red squirrel.  There are numerous dusky grouse and herds of deer within the meadows and timber.  Brown bear roamed the Pine Valley Mountains as late as 1914.
