Mentor High School is a public high school located in Mentor, Ohio. It is the only high school in the Mentor Exempted Village School District (informally, "Mentor Schools"). In the 2008–2009 school year, it shifted from a three-year school (grades 10–12) to a four-year high school (grades 9–12), serving 3,200 students. Mentor High School educates students from Mentor, Mentor-on-the-Lake, and parts of Kirtland Hills and Concord Township in Lake County, Ohio. Mentor High is made up of mainly students from the three Mentor middle schools; Memorial, Shore, and Ridge.
As of 2007[update], it was the largest high school in Ohio.
There are four concert bands at the high school. Freshman Band, Grey Band, Scarlet Band, and Wind Ensemble, at increasing levels of skill. All four bands compete in the OMEA contest.
Mentor has four orchestras in its program, including Concert, Sinfonia, Symphony, and Mannheim. Concert Orchestra is entirely stringed instruments, and requires no audition to join. Sinfonia, created in 2016, is a string-only ensemble for younger students who are committed to practicing but not prepared for Symphony. Symphony Orchestra is the largest group, and consists of both string and wind instruments. Mannheim Chamber Orchestra is the smallest group (consisting of approximately 30 students), and consists entirely of stringed instruments. Mannheim and Symphony both require auditions, but Mannheim is much more selective.
There are four curricular, concert choirs that perform at concerts throughout the year festivals and at OMEA adjudicated events. There are two auditioned Vocal Chamber Ensemble and an auditioned show choir as well. Choristers have the opportunity to perform at an annual Cabaret show and in the OMEA Solo & Ensemble Adjudicated event.

In 2015, the Science Olympiad team went to nationals for the first time in 6 years. After defeating Solon High School and coming in 2nd in the state, behind Centerville, the team traveled to University of Nebraska-Lincoln, placing 16th.
