Marian A. Peterson Middle School, formerly Marian A. Peterson High School, is in Sunnyvale, California. It was a comprehensive, coeducational public high school that operated from 1965 to 1981. The school served students in grades nine through twelve in the Santa Clara Unified School District (SCUSD). Due to declining student enrollment, the school was repurposed as Marian A. Peterson Middle School in 1981 and its student body was absorbed by Adrian C. Wilcox High School.

In 2025, the middle school had 741 students who were almost half Asian and more than a quarter Hispanic.
