Casey Martin (born June 2, 1972) is an American professional golfer and the current men's golf head coach at the University of Oregon.

In May 2006, Martin was named head coach of the University of Oregon's men's golf team in his hometown of Eugene, after working as a volunteer assistant during the 2006 season.

He took a medical leave from coaching during the Ducks' fall 2019 golf schedule, with assistant Brad Lanning taking over until he returned to campus for the spring season (which was ultimately shortened due to the coronavirus pandemic).

In a March 2020 interview with The Register-Guard, the daily newspaper for Oregon's home of Eugene, Martin said about the prospect of losing his leg, "I was grateful that I was able to hold it off for a long time.

He added that he had considered an amputation, recognizing that a prosthesis would enable him to walk without pain, but noted, "If I lose my leg, it would be an above-the-knee deal, and it's pretty risky for my situation anyway.

At the time of the interview, Martin was scheduled to travel to Washington state to be fitted for a special carbon-fiber leg brace that could potentially redirect his body weight in a way that would allow the fracture to heal.
