Jim Rex (born November 21, 1941 in Toledo, Ohio) was the 16th South Carolina Superintendent of Education. He ran for the position in 2006 as a Democrat, against Karen Floyd, a Republican. Rex defeated Floyd by only 455 votes, the closest margin of victory in a statewide election in South Carolina's history. He was sworn-in as Superintendent on January 10, 2007, replacing fellow Democrat Inez Tenenbaum.
