Wallace Falls State Park is a public recreation area that encompasses 1,380 acres (560 ha) along the Wallace River in Snohomish County, Washington.

The state park is located on the west side of the Cascade Mountains with an entrance point one mile (1.6 km) northeast of the community of Gold Bar.

The park features three waterfalls, three backcountry lakes, old-growth coniferous forests, rushing mountain rivers and streams, and the evidence of its logging history in the ruins of railroad trestles, disused railroad grades, and springboard notches in stumps.

[2] The name "Wallace" is a corruption of the last name of Joe and Sarah Kwayaylsh, members of the Skykomish tribe, who were the first homesteaders in the area.

The park originated with the state's purchase of land from the Weyerhaeuser Timber Company in 1971.
