Lyndsay Stephen (22 March 1956 – 25 February 2021) was an Australian professional golfer. Stephen had much success early in his career, winning the South Australian Open at the age of 24. There were high expectations for him though he did not always meet them, recording at least seven runner-up finishes during the remainder of the 1980s but rarely winning. In the early 1990s he briefly quit tournament golf, focusing to work as a coach. However, he shortly returned and recorded some late career highlights, including victories at the 1996 South Australian PGA Championship and 2010 Australian PGA Seniors Championship.
