Richland High School is a public secondary school in the northwest United States, located in Richland, Washington. The school was founded as Columbia High School in 1910 to serve the educational needs of the small town of Richland. The building was replaced with a much larger structure by the U.S. Army Corps of Engineers in 1946 as the development of the neighboring Hanford Engineering Works brought an influx of employees to the region to support the war effort.
