West Union Creek is a 4.5-mile-long (7.2 km) stream originating on the eastern slope of Kings Mountain in the Santa Cruz Mountains, in San Mateo County, California, United States. It flows easterly down to the valley formed by the San Andreas Rift where it turns near the Phleger Estate to flow southeasterly on an unusually level course (for a mountain stream) to Adobe Corner in the town of Woodside where it then joins Bear Gulch Creek. This in turn flows to the San Francisquito Creek and ultimately, the San Francisco Bay.
