Bear Creek (Lushootseed: tubaʔal) is a tributary of the Sammamish River in King County, Washington, United States.

The stream flows approximately 12.4 miles (20.0 km) from its source at Paradise Lake near Maltby to a confluence with the Sammamish River at Marymoor Park in Redmond.

Some tools found at the site held DNA from ice-age animals such as bison, deer, bear, sheep, and salmon.

The project hopes to return the industrialized creek to a "more natural state" in order to support salmon habitat and other wildlife.
