Joseph Knowland State Arboretum and Park is a park located in the Grass Valley neighborhood of Oakland, California. It was formerly a state park, and is now the property of the City of Oakland. The Oakland Zoo occupies the developed western lowlands of the park, just off I-580.

The largest and most pristine portion of the park is undeveloped, and yet is the most accessible to park users. The western highlands and northern slopes are currently a thriving hotspot for rare native plants and wildlife.
