Brush Creek or Rincon Creek is a tributary of Santa Rosa Creek in Sonoma County, California. Brush Creek rises in the southern slopes of the Mayacamas Mountains within Sonoma County.
The lower reach of the creek is a suburban medium density residential area in the city of Santa Rosa, and that reach of Brush Creek has been restored during the 1990s under a U.S. Environmental Protection Agency grant to promote steelhead migration and spawning. Further restoration and incorporation into citywide park planning is currently underway as of 2006.
