Mt. Ararat High School is a high school in Topsham, Maine, United States. It is part of Maine School Administrative District 75 and it is the only high school in that district.

In 1973, Mt. Ararat High School, then known as Mt. Ararat School, and assigned building number 73 to commemorate the year of launch, opened for the students of its four sending towns: Bowdoin, Bowdoinham, Harpswell, and Topsham, Maine. For the first 22 years of its existence, the school provided education to students in grades 7-12. Starting in fall 1995, due to overcrowding, middle school students in grades 7 and 8 attended school at a newly formed Mt. Ararat Middle School, first housed in the old Brunswick High School building, in the nearby town of Brunswick. At that time, the name of the original school was changed to Mt. Ararat High School. In 2001, middle school students, faculty, and staff moved into a new building, now the Mt. Ararat Middle School. The name Mt. Ararat School was taken from the name of the hill that lies behind the school, the site of a fire tower, with a cell tower at its crest. The old school's address of 73 Eagles Way, was first used in the late 1990s, which remained the name of the old school's address until it was demolished in 2020. The name was in honor of the school's inaugural year and the school's mascot.

In August 2010, MSAD No. 75 received acceptance on an application to the state to either renovate or build a new high school. The then superintendent, Brad Smith, presented the district as hoping to be eligible for building a new school. The location for the new high school was to be the athletic fields. The plans for the new high school were approved in 2017 and construction began in 2018. On September 8, 2020 the new Mt. Ararat High School opened its doors to students for the first time.

The new Mt. Ararat High School was completed in 2020, and the former building was demolished that same year.

As of 2021, Mt. Ararat High School has approximately 865 students and 126 faculty members. The principal is Dr. Chris Hoffman, and the two assistant principals are currently Mr. Deron Sharp and Ms. Jessica Belanger. The Athletic Director is Geoff Godo.
