Rittman High School is a public high school in Rittman, Ohio, United States. It is the only high school in the Rittman Exempted Village Schools district. They are nicknamed the "Indians", which comes from the old Rittman Chippewa Salt Company's (now known as Morton Salt Company) logo of a Native American's head. Red and white were the school colors until 1940 when black was added. Since the 2005-2006 school year, the eighth grade class has been included in the high school. A new high school was built and opened in 2011 on the same property as the previous building.
