Chatsworth High School is a public secondary school located in Chatsworth in the San Fernando Valley of Los Angeles, California, U.S..
As of the 2005–06 school year, the school had an enrollment of 3183 students and 117.8 classroom teachers (on an FTE basis), for a student-teacher ratio of 27.0.
The campus was built with one-story buildings around a central quad as land was inexpensive and an open, outdoor feeling was consistent with the area. The administration building anchors the southeast end of the quad, while the cafeteria and auditorium anchors the northwest end. Athletics are on the other side of the internal roadway.
Chatsworth's band was the last LAUSD band to go the Pasadena Tournament of Roses Parade, as the system of selecting a schools band was changed to selecting players from each band.
Chatsworth's Drama Department participates in Fall and Shakespeare DTASC Festivals every year, earning recognition in acting and technical design. The department puts on two productions every year and is Thespian Troupe #2314 in the National Honor Thespian Society. Many notable alumni artists have come out of Chatsworth High School's Drama Department such as Val Kilmer, Mare Winningham and Kevin Spacey, who recently co-produced a documentary airing on HBO, "Shakespeare HIgh" featuring Chatsworth's Drama Department.
