Thomas K. Bohannan (born c.1955 in Mobile, Alabama) is an American Thoroughbred racehorse trainer.
He grew up in Lexington, Kentucky and as a young man became a hotwalker, groom, and racing stable foreman.
The following year Prairie Bayou finished second in the Derby, then gave Tom Bohannan his second consecutive victory in the Preakness.
Fatally injured in the Belmont, Prairie Bayou was posthumously voted 1993's U.S. Champion 3-Year-old Colt.
After a difficult year in which they won only four of thirty-five races, in October 2007 Bohannan and John Ed Anthony parted ways.
