Freeman's Park was a baseball park in Emeryville, California. It was the home field of the Oakland Clamdiggers of the California State League during 1899-1902; and the Oakland Oaks of the Pacific Coast League in 1903 and then again during 1907-1912. The venue was established by a developer named William Freeman Jr. by about 1897. His father, British-born William Freeman Sr., was likewise a developer.[Oakland Tribune, March 18, 1915, p.20]
