The Delta Meadows is a state park in Rio Vista, California. It was created to protect and preserve one of the last remaining portions of the northern Sacramento-San Joaquin River Delta that has some remnants of the natural conditions that was once prevalent in the area before the European settlement.

Noted for its natural and cultural historical significance, the Delta Meadows is popular for fishing, canoeing, and hiking. Visitors can find Native American occupancy sites as well as some traces of early farming techniques like levee building and slough dredging. It is also rich in riparian plant and animal life like the river otter, Sacramento chub, and delta smelt.

Also known as the Delta Meadows River Park, the Delta Meadows is currently closed to the public.
