Diamond Ranch High School (or DRHS) is a high school that serves students from Diamond Bar and Phillips Ranch, California, United States, and is operated by the Pomona Unified School District (PUSD) in Pomona, California. Diamond Ranch's athletic teams compete in the Hacienda League of the CIF Southern Section.


The school was designed in an expressionist modern style by Morphosis and Thomas Blurock Architects, led by architect Thom Mayne of Morphosis.[2] It is situated on a steep hillside on land previously considered unusable.[3][4][5] The school's unique architectural design was recognized in the book Morphosis/Diamond Ranch High School.

Because of its modernist architecture, size and location in California, the school has appeared in movies such as The Cell, Orange County, Serenity, Live Free or Die Hard,[6] and The Thinning. It has also appeared in several television commercials—including one for Buick.


The name was derived from its geographical location at the junction between the City of Diamond Bar and Phillips Ranch, in Pomona, California. The school is also near to the city of Chino Hills, California.
