Middlesex School is a co-educational, non-sectarian, day and boarding independent secondary school for grades 9-12 located in Concord, Massachusetts. It was founded as an all-boys school in 1901 by a Roxbury Latin School alumnus, Frederick Winsor, who headed the school until 1937. Middlesex began admitting girls in 1974. The school is a member of the prestigious Independent School League and is one of five schools collectively known as St. Grottlesex.

The school was named for the county Middlesex in which it stands. The campus was designed by the Olmsted Brothers architectural firm, and the firm Peabody and Stearns designed most of the main buildings. A recent addition is the Clay Centennial Center, completed in 2003, which hosts science and math classes as well as an observatory with an 18-inch research grade telescope.

The school is 70% boarding students and 30% day students. In 2014-15, boarding students came from 26 states and 21 countries with 70% of all boarders residing outside of Massachusetts. The school accepted 18% of students who applied to enter in for 2014-2015. In that year, 28 percent of students received financial aid from a $4.6 million financial aid budget.
