Bear Creek is a stream in eastern Sonoma County, California, United States, a tributary of Sonoma Creek.
The stream originates near the SonomaâÂÂNapa county line, about north of the northern Bald Mountain summit. It descends first to the west and then to the south, emptying into Sonoma Creek just west of Sugarloaf Ridge State Park.
As of 2000, Bear Creek supported steelhead trout.
