Anthony David Graham (born 23 May 1946) is a former professional golfer from Australia. Born in Windsor, Australia, Graham turned professional in 1962 at age 16 and spent much of his career in the United States, playing on the PGA Tour. Turning age 50 in 1996, he joined the Senior PGA Tour, later known as the Champions Tour. Although known for his success in the U.S., he won events on six different continents in his career, an achievement he shares with Gary Player, Hale Irwin and Bernhard Langer. In 1976, after several successful years on tours around the globe, Graham came to prominence with two wins on the PGA Tour, and then came from behind to secure a victory over the reigning champion Hale Irwin in the Piccadilly World Match Play Championship.
