Maud Williamson State Recreation Site, State recreation site in Yamhill County, United States.

Maud Williamson State Recreation Site is a recreation area in Yamhill County with open fields and dense Douglas fir forests that provide shade and natural habitats for wildlife. The grounds include volleyball courts, horseshoe pits, restrooms, and a covered picnic shelter available for group use.

Maud Williamson, a longtime teacher at the Wheatland school, died around 1933 and willed her timberland and house to the State of Oregon in memory of her mother, Ruby T. Williamson. A bronze plaque commemorating the donation was placed in the park in 1934. Part of the park lies on the original Donation Land Claim of Adam Matheny, son of Daniel Matheny, who established the Wheatland Ferry.

The adjoining Charles S. Williamson House is a Queen Anne-style house built in 1890 by Maud Williamson's father, who served as Wheatland's postmaster for 12 years. Maud Williamson lived there with her brother. The house is not open to the public.

The recreation site is most accessible during warmer months and offers plenty of shade under the trees throughout the grounds. Visitors planning group gatherings should arrange in advance for the covered picnic shelter, as it requires booking.
