Stonefield Beach State Recreation Site, State recreation area on Oregon Coast, United States.

Stonefield Beach State Recreation Site is a state park in Lane County, Oregon, administered by the Oregon Parks and Recreation Department. Tenmile Creek flows through the park and empties into the Pacific Ocean. The site lies about 2 metres above sea level, with wooded hills rising inland and Yachats roughly 9.6 km to the north.

The site became part of Oregon's state park system between 1967 and 1969 through land purchases from private owners. These acquisitions established what visitors see today as a public coastal recreation area.

Stonefield Beach State Recreation Site lies in Lane County, about 9.6 km north of Yachats, where Tenmile Creek meets the Pacific. The surrounding hills are covered in coniferous forest, and the climate is mild, averaging around 8 °C, with August the warmest month at about 16 °C.

The site stays open year-round with restroom and picnic facilities, though parking may close during bad weather or high tides. Plan your visit around the tide schedule to get the best views of the tide pools and avoid slippery rocks.
