Robert George MacDonald (24 February 1885 – 29 March 1960) was a Scottish-American professional golfer and club maker who played in the early 20th century.

He and his family emigrated to the United States in 1910 and his first posting as a professional was in New Jersey and he later took a job at Hyde Park Country Club in Cincinnati, Ohio.

[1][2] The Aberdeen Journal described MacDonald as "a big brawny Scotsman of the Braid type, and has all the markings of a first-class player".

MacDonald took up a post at North Berwick with his brother-in-law, Donald MacKay, and James Watt.

Amateur champion Jerome Travers captured his only U.S. Open title, one stroke ahead of runner-up Tom McNamara.

He found himself in the semi-finals against Jim Barnes and finally succumbed by the score of 5 and 4, finishing the tournament tied for third place.

[2] In the book's preface he wrote, "It is probably beyond argument that the golf stroke, apart from the putt, is the most highly technical method of hitting a ball in the whole realm of sport".
