Acalanes Union High School District is a public high school district in Contra Costa County, located in the Bay Area of California. The district takes its name from Rancho Acalanes, an 1834 Mexican rancho grant which occupied much of the area from Orinda to Lafayette. The district operates four high schools.


It currently has five schools: Acalanes High School in Lafayette, Campolindo High School in Moraga, Las Lomas High School in Walnut Creek, Miramonte High School in Orinda, and The Acalanes Center for Independent Study in Walnut Creek. A fifth campus, Del Valle High School located in Walnut Creek was closed at the end of the 1978–1979 school year and remaining students were transferred to Acalanes, Campolindo, and Las Lomas High Schools. The district's alternative school, Del Oro High School, opened on the former site of Del Valle High School, closed following the 2009–2010 school year, although the district still operates Acalanes Adult Education at the Del Valle Education Center in Walnut Creek. As of 2023, Del Valle is also operational as The Acalanes Center for Independent Study. John Nickerson has served as the district's Superintendent since May, 2011.
