2003 All-Big 12 Conference football team

The 2003 All-Big 12 Conference football team consists of American football players chosen as All-Big 12 Conference players for the 2003 NCAA Division I-A football season. The conference recognizes two official All-Big 12 selectors: (1) the Big 12 conference coaches selected separate offensive and defensive units and named first- and second-team players (the "Coaches" team); and (2) a panel of sports writers and broadcasters covering the Big 12 also selected offensive and defensive units and named first- and second-team players (the "Media" team).
