Salmon Creek is a 26-mile (42 km) tributary of Lake River in Clark County in the U.S. state of Washington.

Beginning from its forested headwaters on Elkhorn Mountain, Salmon Creek passes through rural, agricultural, residential, and urban areas before flowing into the river just north of Vancouver Lake.

Despite this, steelhead, coho salmon, and coastal cutthroat trout use about 43 miles (69 km) of the basin's streams.

The county restored more than 650 feet (200 m) of stream channel west of the bridge, which has improved salmon and steelhead passage.
