Skookumchuck Dam is an earthen dam located on the Skookumchuck River in Washington state, east of Bucoda and Tono. The embankment was built in 1970 to supply water for a TransAlta coal plant in the Hanaford Valley.

Various proposals have been introduced to use the dam as a flood mitigation tool or have the levee removed to improve river flow and the ecosystem. The energy facility is planned to be decommissioned in 2025 and water rights given to the city of Centralia.
