Robert Maitland Dinwiddie (born 29 December 1982) is an English professional golfer.

He was assisted by College Prospects of America to gain a golf scholarship at Tennessee State University, and was the number one ranked English golfer.

[1] Dinwiddie won Welsh and Scottish Amateur Open Stroke Play Championships in 2005, and when he also claimed the English Amateur Open Stroke Play Championship, otherwise known as the Brabazon Trophy, in 2006, he became the first person to hold all three titles at the same time.

[4] He made an impressive major championship début, finishing in a tie for 36th place.

After a difficult 2009 season, Dinwiddie returned to the Challenge Tour for 2010, where he promptly won the Kenya Open,[5] the second event of the year.
