Ellwood P. Cubberley High School (1956–1979), known locally as "Cubberley", was one of three public high schools in Palo Alto, California. The site of the closed school is now named Cubberley Community Center and used for many diverse activities.

Opened in 1956, Cubberley High was located at 4000 Middlefield Road. The high school was named after Ellwood Patterson Cubberley, the Dean of the Stanford Graduate School of Education and pioneer of educational administration.

The school was finally closed in 1979 as a reaction to declining enrollment and decreased revenues following Proposition 13. The other local high schools Gunn High School and Palo Alto High School had been created on friendly land transfers from Stanford University and if educational use was to be terminated, the land would revert to the university for the value at the time of transfer. The Palo Alto Unified School District board, requiring an infusion of cash, determined Cubberley could be sold at more contemporary rates. Later it was discovered that it could only be sold to a non-profit organization. That has resulted in part of the campus being converted into the Cubberley Community Center, on an annual lease from the school district to the City of Palo Alto.

The Cubberley Cougars competed in the SPAL of the CIF Central Coast Section. The school won its only CCS Championship in track and field in 1979, just days before it would close forever.

Cubberley was the scene of The Third Wave experiment by teacher Ron Jones in 1967, which was an elaborate social experiment to better understand fascism. The experiment was later portrayed in a film and television.

A KQED special program from 1970 features a three-day teaching conference at Cubberley High School that focused on ecology and population issues.

Numerous societal tensions played out at Cubberley from 1967 to 1969 that were the subject of Sylvia Berry Williams' 1970 book Hassling, which gave the school national attention.

For many years the use of the Cubberley location has been subject to local community debate. According to local news in 2011, enrollment projections done by Palo Alto Unified School District suggested Cubberley may need to be reopened as a fourth middle school by 2015 and ultimately be reopened as a third high school by 2021. However these plans were delayed by the city, and the city and the school district have been in discussions.
