Oak Hills is a census-designated place (CDP) and neighborhood in Washington County, Oregon, United States. The CDP population was 11,903 at the 2020 census. It is on unincorporated land north of Beaverton, west of Cedar Mill, and south/southeast of Bethany. The CDP is roughly bounded by the Sunset Highway on the south, West Union Road on the north, Northwest 174th Avenue on the west, and Northwest 143rd Avenue on the east. The U.S. Postal Service has assigned Beaverton addresses to the area. Fire protection and EMS services are provided through Tualatin Valley Fire and Rescue.

The Oak Hills neighborhood is substantially smaller than the CDP, and is contained within the area bounded by Cornell Road on the south, West Union Road on the north, Bethany Boulevard on the west, and Northwest 143rd Avenue on the east. It was a planned community and was built in the 1960s. The first ten homes were completed in May 1965, the first of about 650 planned, in an area of approximately 250 acres (100 ha). Oak Hills today includes around 650 residences, of which 627 are single-family homes. It is managed by the Oak Hills Homeowners Association (OHHA).

The neighborhood was listed on the National Register of Historic Places in 2013, as the Oak Hills Historic District. It includes 29 homes designed by home builder Robert Rummer.
