Silver Star Mountain is an extinct volcano in the southwestern Cascade Mountains in the U.S. state of Washington, named for the pattern of five prominent ridges that radiate from the summit in the shape of a star. At an elevation of 4,390 feet (1,338 m), the two peaks of the mountain dominate the horizon east of Vancouver, Washington. In September 1902 Silver Star Mountain was the center of the Yacolt Burn, the largest fire in Washington history, which took 38 lives and burned over 238,000 acres (960 km²) (the smoke was so thick that street lights glowed at noon in Seattle 160 miles (260 km) away).

With the loss of vegetative ground cover, a series of rockslides occurred on the slopes of Silver Star Mountain and neighboring uplands that were also affected by the fire. The result is a landscape that has resisted natural reforestation for more than a century. Wildflowers and other species of flora that thrive above the timberline elsewhere in Washington are found here despite the altitude being 2,000 feet (600 m) lower than the timberline usually is in the region.

Silver Star Mountain is the center of a pluton of magma that was injected into the area 20 million years ago and cooled to solid rock under the surface, producing small deposits of gold, zinc, copper, zeolites, quartz and calcite. Small abandoned gold mines are found in creek bottoms throughout the area.

The higher north peak was once the site of a fire lookout. There is an unobstructed 360 degree view of the entire Portland, Oregon metropolitan area, as well as views of the Columbia River Gorge, the Pacific Coast Range, Mount Saint Helens, Mount Rainier, Mount Adams, Mount Hood, and Mount Jefferson. An archaeological site with Native American artifacts is found a short walk south from the summit area.

The area is accessed from the west by a trailhead on Forest Road 1200 at Grouse Creek Vista, which is a pass between Silver Star Mountain and Larch Mountain. Forest Road 4109 scales the northern ridge to a trailhead 1.9&miles from the summit.

The highest point in Clark County, Washington is Sturgeon Rock, a basalt outcrop that lies on the county line just west of the Silver Star summit. For many years an error on United States Geological Survey topographical maps has misnamed a broad wooded peak lower on the ridge near the Tarbell Trail as Sturgeon Rock.
