Captain Harold Robert Buckley (4 April 1896 – 13 June 1958) was a World War I flying ace credited with five aerial victories.

Lieutenant Buckley was on a patrol protecting a French biplane observation machine, when they were suddenly set upon by six enemy planes.

Lieutenant Buckley attacked and destroyed the nearest, and the remainder fled into their own territory.

He then carried on with his mission until he had escorted the allied plane safely to its own aerodrome.

On the next day, while leading a patrol, he met and sent down in flames an enemy plane while it was engaged in reglage work.
