Oak Hills is a special area in Washington County, Oregon, United States. It is called a census-designated place (CDP). This means it's a place where many people live, but it's not officially a city or town.

In 2020, about 11,903 people lived in the Oak Hills CDP. It is located on land that is not part of any city. This land is north of Beaverton, west of Cedar Mill, and south of Bethany. The area is bordered by the Sunset Highway to the south and West Union Road to the north.

The U.S. Postal Service uses Beaverton addresses for homes in Oak Hills. Fire and emergency services are provided by Tualatin Valley Fire and Rescue.

The Oak Hills neighborhood is a bit smaller than the CDP. It is a planned community that was built in the 1960s. A planned community is an area designed and built all at once. The first homes were finished in May 1965. There were about 650 homes planned for an area of about 250 acres. Today, Oak Hills has around 650 homes, mostly single-family houses. The neighborhood is managed by the Oak Hills Homeowners Association (OHHA). This group helps keep the community running smoothly.

In 2013, the neighborhood was added to the National Register of Historic Places. This means it is recognized as an important historical area. It is known as the Oak Hills Historic District.
