Ona Beach State Park, State coastal park near Seal Rock, Lincoln County, Oregon, United States

Ona Beach State Park is a state park straddling Beaver Creek about halfway between Newport and Waldport, Oregon. It is part of Brian Booth State Park, formed in 2013 by merging Ona Beach with Beaver Creek State Natural Area. The park covers 886.32 acres and includes beach access, kayaking, and hiking trails.

The land was bought from private owners between 1938 and 1968, including a 10-acre gift from Lincoln County in 1963. In 2013 the park was renamed Brian Booth State Park to honour Brian Booth (c. 1937–March 2012), the first chair of the Oregon State Parks and Recreation Commission. Beaver Creek State Natural Area, merged with the park in 2013, had opened to the public on October 1, 2010.

The name Ona comes from Chinook Jargon, in which it means razor clam. The park was renamed Brian Booth State Park in 2013 to honor the first chairperson of the Oregon State Parks and Recreation Commission, Brian Booth (c. 1937–2012).

The day-use area has picnic tables, grills, restrooms, and direct beach access with parking available in multiple locations. Plan your visit around the tide schedule, as water levels affect which parts of the park are easily accessible.

Before the Coast Highway was completed, the beach between Newport and Seal Rock served as an access road: motorists drove at low tide, following the mail carrier who knew the best way across Beaver Creek. The park was renamed Brian Booth State Park in 2013 to honour the first chair of the Oregon State Parks and Recreation Commission (c. 1937–March 2012).
