Waterloo School is a former school in Waterloo, Ohio. Planning for the facility began in 1916 and became a reality in the following year using the second floor of a local store.1 The school then moved into the former Waterloo Methodist Church building until 1930.

Plans for a permanent school structure began in 1928 and a bond issue was passed in 1929. The new Waterloo School opened in 1930. It closed in 1961 upon completion of the Symmes Valely School.1
