Herbert Haydn Barker (1883 – 14 June 1924) was an English professional golfer and golf course architect who played in the early 20th century.

Barker had a successful amateur career, winning several tournaments in Great Britain in the early 1900s representing Huddersfield Golf Club.

But he also discovered less challenging courses and soon began designing and remodelling layouts with the intention of elevating the game in the United States.

[3] Barker took a two-month leave of absence from the Country Club of Virginia and sailed back to Britain on 30 July 1915[3][8] to enlist in the military, joining the Royal Flying Corps.
