James N. Gamble Montessori High School (less formally known as Gamble Montessori) is a public high school in Cincinnati, Ohio, United States.

[2] Increasing demand for secondary Montessori education in the city prompted the creation of this program, the second Montessori public junior high/high school in Cincinnati Public Schools, in 2005.

The program was originally housed in the Dater Montessori Elementary School building, before moving to the Jacobs Center in the fall of 2007, when it was renamed Westside Montessori High School.

[3] Gamble Montessori is currently located in Westwood at the original building.

On April 30, 2012, the CPS Board of Education approved taking out a $26.8 million loan for green renovations of several schools, including $6.9 million for Gamble Montessori.
