Tommy Morrison born January 2, 1969, is an American heavyweight boxer and a former World Boxing Organization champion. He lost only three out of a total of 52 professional fights. Morrison's nickname, "The Duke," is based on disputed claims that he is a grandnephew of Hollywood star John Wayne. Morrison was a co-star with Sylvester Stallone in the 1990 boxing movie Rocky V.

Morrison's professional boxing career effectively ended when he tested positive for HIV in 1996. Beginning in 2006, Morrison attempted a comeback, stating that he did not have HIV and, later, that HIV is a "myth." His claims are refuted by boxing and medical authorities.

Beginning at the age of 13, Morrison entered fifteen "toughman" contests using a fake ID (the minimum age for contestants was 21). He told The New York Times that he lost only one of these contests.
