Maine East was known as Maine Township High School when it was built in 1929 as a replacement for the original Maine Township High School, which itself had been built in 1902. Until 1959, when Maine West High School was built, it was the only school in the district. The school was built with an indoor rifle shooting range and a swimming pool. Over the years, the shooting range was closed and the swimming pool closed with a larger modern pool opened in a new section of the building.
