The 2009 Kansas Jayhawks football team (variously "Kansas", "KU", or the "Jayhawks") represented the University of Kansas in the 2009 NCAA Division I FBS football season, which was the school's 120th season and the eighth and final year under Mark Mangino, who resigned following the season under pressure from both an internal investigation into his treatment of players and discontent from the season's results. It was Ed Warinner's third season as offensive coordinator and fifth year overall. The Jayhawks played their home games at Memorial Stadium in Lawrence, Kansas and were members of the Big 12 Conference
