Felton Grandison Clark (October 13, 1903 – July 5, 1970) was an African-American academic administrator from Louisiana. He served as the president of Southern University (SU), a historically black university and land-grant college in Baton Rouge, Louisiana, from 1938 to 1969. During this period, he led decades of expansion that resulted in the number of students increasing from 1,500 to over 11,000. By the time of his retirement, SU had grown to be America's largest historically black university by enrollment.
