Noel Anthony Ratcliffe (17 January 1945 – April 2024) was an Australian professional golfer.

Ratcliffe turned to golf late for a future professional, and didn't own a set of clubs until he was twenty-one. At university he studied pharmacy and worked for an insurance company and in public service.^{[citation needed]}

In 1974, Ratcliffe turned professional. Like many Australian golfers of his era, he divided his time between the PGA Tour of Australia and the European Tour. In his regular career he won three titles in Australasia and two in Europe, where his best year was 1978 when he finished 11th on the Order of Merit.

After turning fifty he was successful on the European Seniors Tour, where he topped the Order of Merit in 2000, made the top five on four other occasions, and won eight tournaments.

Ratcliffe died in April 2024, at the age of 79.
