River Ridge High School, commonly referred to as Ridge, is an American high school located in Lacey, Washington, United States and is one of three comprehensive high schools of the North Thurston Public Schools. It was established in 1993 and named for its proximity to the geographical ridge of the Nisqually River valley. It earned its school nickname due to its location within the Hawk's Prairie area of Thurston County off Exit 111 of Interstate 5, serving students living in Mushroom Corner and Tanglewilde-Thompson Place.River Ridge and its feeder school, Nisqually Middle School, serves many students with parents who are on active duty or have retired from the military due to its proximity to Joint Base Lewis-McChord. River Ridge was constructed as a community solution to handle the over-flowing capacities of neighboring Timberline and North Thurston High Schools in the late 1980s-early 1990s, producing a more diverse student body population than the other two high schools in the district.
