Winchester High School is a comprehensive 9–12 high school located in Winchester, Massachusetts, United States. Founded in 1850, it moved into its current location in the spring of 1972. Ranked 16th among Massachusetts High Schools, close to 98% of students graduated in 2016, with about 96% of those continuing to higher education.

A major three-phase reconstruction and expansion of the school started in 2014 and was completed in September 2017. Most of the school was rebuilt using the original structural frame.  After the complete redesign of the interior of the building, approximately 75% of classrooms now have exterior windows and direct day-lighting versus 25% in 1972. The original internal courtyard was enclosed to create the 2-story dining commons and assembly space.  Winchester High School remained in use during construction.
