    Mason-Clark Middle School, in East St. Louis, Illinois, is a large middle school serving students in grades 5-8.

    Mason-Clark Middle School is named for the great community members Dr. William Mason and the late Douglas W. Clark. Douglas W. Clark was a great Math educator for over 30 years in East St. Louis and is the namesake of the Math-A-Thon each year. Dr. William Mason was a former mayor of the city of East St. Louis and had been Superintendent of School District 189.
