Silver Creek is an unincorporated community in Lewis County, Washington, United States. Silver Creek is located along U.S. Route 12 near its junction with Washington State Route 122, 5 miles (8.0 km) west of Mossyrock. Lake Mayfield is accessible 3.5 miles to the east.

The town takes its name from a nearby creek of the same name. One of two brooks labeled Silver Creek in Lewis County, the silver moniker was believed to be taken from the colorful effects of the waters near the community. A second theory posits that reflections off the creek bed signified the possibility of silver in the waterway.

One of the earliest non-indigenous settlers in the area was the John Tucker family, creating a homestead in 1868. The first post office was established in the Tucker home and a family member oversaw postal duties in the community for nearly five decades. The post office, given the name Silver Creek, has been in operation since 1875.
