Orenco Woods Nature Park, Nature park in Hillsboro, Oregon, US

Orenco Woods Nature Park is a nature park in Hillsboro, Oregon, made up of wetlands, forest areas, and open meadows. Trails run through these different zones, letting visitors move from one habitat to another on foot.

The site was a nine-hole golf course owned by the Hillsboro Elks. Venture Properties bought it in 2007 and planned 252 homes, but the Great Recession and resident appeals led by Jim Lubischer stalled the project. Hillsboro and Metro bought the land in 2011 for $4 million, and the park opened on February 4, 2017.

The park keeps the name Orenco from the neighbourhood and from the nine-hole golf course owned by the Hillsboro Elks that once occupied the land. The Malcolm McDonald House, listed on the National Register of Historic Places, stands inside the park boundaries. The Rock Creek Trail is planned to link the site with Orchard Park upstream and Noble Woods Park downstream.

The park is bounded by Cornelius Pass Road on the east and the MAX Blue Line tracks on the north. Rock Creek runs through the 42-acre site, and the Rock Creek Trail is planned to link it with Orchard Park upstream and Noble Woods Park downstream. Restrooms, a picnic shelter, trails and bridges are on site.

The Malcolm McDonald House, listed on the National Register of Historic Places, stands inside the park boundaries. The city sold 9.7 acres at the southeast corner in January 2013 to help fund the park's development.
