The Fayetteville-Manlius School District is located in Manlius, New York, a town in Onondaga County. The district serves the Town of Manlius and the neighboring Town of Fayetteville. The villages of Manlius and Fayetteville had independent school districts until 1951, when they merged. A two hundred year old oak tree nestled by one of the schools in the district inspired the school’s alma mater hymn and yearbook titles. The characteristics of the tree, such as its strength and dependability, are reflected in the values of the Fayetteville-Manlius School District. The school’s mascot, the Hornet, is also inspired by the tree, as hornets were found living in the giant Oak.
The Manlius School was a top military school in the United States in the mid-20th century. It had been founded as the St. John's School in 1869, then reorganized as St. John's Military School in 1881. The Manlius School, as it became known as, faced dwindling attendance and merged with Pebble Hill School in 1970.
