Wayne Desmond Grady (born 26 July 1957) is an Australian professional golfer.

He began his career on the PGA Tour of Australia and had much early success, winning the 1978 CBA West Lakes Classic.

He also played extensively on the European Tour during this era, winning the 1984 German Open.

However, Grady is probably best known for his 1990 PGA Championship victory where he defeated Fred Couples down the stretch.

He was also runner-up at the 1989 Open Championship, losing with fellow Australian Greg Norman in a playoff to American Mark Calcavecchia.
