Mountain View High School (MVHS) is located at 3535 Truman Avenue, Mountain View, California, 94040. It is one of two Mountain View-Los Altos Union High School District public high schools - the other being Los Altos High School. The three main feeder schools are Graham Middle School, Crittenden Middle School, and Blach Intermediate School.

Public education in Mountain View, California dates as far as 1858, but lacked a high school. Before Mountain View High School was created in 1902, students living within the town's limits commuted by train from Downtown Mountain View Station on Castro Street to attend either Palo Alto or Santa Clara High Schools. In August 1902, the town of Mountain View opened its first school at the corner of El Camino Real and Calderon Streets, named Mountain View Union High School.^{[citation needed]} By the dawn of the 1920s, the high school saw a spike in enrollment and the campus was unable to accommodate any more students. In 1922, the school district built a new campus at a new location on Castro Street. The new campus first opened its doors in late August 1924. Several years later, in 1933, the opening of Moffett Field pushed the expansion of the campus with additional facilities to accommodate military children.

By the 1950s, Mountain View Union High School was once again facing challenges with a growing student body and, in 1956, the district added Los Altos High; in the once small rural town of Los Altos. By 1961, the district added an additional high school near Grant Road at the corners of Truman and Bryant. This was named Chester F. Awalt High School, the first superintendent of the district. Mountain View Union High School was closed in 1981 due to declining enrollment. Mountain View School District (known today as MVLA) decided to sell the original school buildings back to the city and relocate to the Awalt High School location, changing Awalt's name to Mountain View. Los Altos High School adopted the MV school colors and mascot. Thus, Mountain View became the black and gold Spartans and Los Altos dropped the Knights and became the blue and gray Eagles.

The high school holds an open enrollment policy: any student may register for any class being offered at the school, regardless of a student's grade. Mountain View High, like most Bay Area schools, offers all 8 of the AP advanced STEM classes. Environmental Science AP and Psychology AP were added as class options for the academic year of 2013–2014.
