Troy Donahue (born Merle Johnson Jr., January 27, 1936 – September 2, 2001) was an American film and television actor and singer. He was a popular sex symbol in the 1950s and 1960s.

His father was Merle Johnson, the manager of the motion-picture department of General Motors. His mother, Edith Johnson, was a retired stage actress. Donahue attended a New York military academy, where he met Francis Ford Coppola. When Donahue was 18, he moved to New York and got a job as a messenger in a film company founded by his father. He was fired, he says, because he was too young to join the union. He attended Columbia University and studied journalism. He trained briefly with Ezra Stone, and then moved to Hollywood.
