Ferdinand "Andy" Geiger (born March 23, 1939) is an American former athletic director at six different institutions, most recently holding that position from May 10, 2012, to August 30, 2013, at the University of Wisconsin-Milwaukee.
His most notable time as an athletic director was when he spent 11 years at the helm of the largest athletic department in the US at Ohio State University, during some of which time he was flanked by controversy over various dealings regarding the former OSU running back, Maurice Clarett.
During his 11-year stay at the Pac-10 school, Stanford won a total of 27 national championships and was considered one of the leading programs in intercollegiate athletics.
As a result of his decision in 2003 to end Maurice Clarett's football scholarship because of alleged violations of the amateur clause, Geiger was widely criticized.
He became the third athletic director there within a two-year span, succeeding Rick Costello who resigned in April 2012.
