Sycamore Valley Regional Open Space Preserve is a regional park in Contra Costa County, California, outside of Danville, California, United States that is part of the East Bay Regional Parks (EBRPD) system.
Sycamore Valley preserve began when the EBRPD acquired 328acres south of Camino Tassajara in 1989, naming it the Sherburn Hills unit. Ten years later, the district obtained 255acres north of Camino Tassajara from the Town of Danville, plus 106acres from Wood Ranch developers. The result was a 361acres tract named the Short Ridge unit. These two names are still used to designate the southern and northern parts of the preserve, respectively. Other small acquisitions have brought the preserve to its present size of 696acres.[1]

The park officially opened to the public on September 25, 2005.[2]
