Herbert Henry McKenley OM (10 July 1922 – 26 November 2007) was a Jamaican track and field sprinter.

He competed at the 1948 and 1952 Olympics in six events in total, and won one gold and three silver medals.

[1] Perhaps because of his success across the wide variation of distances, McKenley was known to have an uneven pace, blasting out to an early lead, but slowing towards the end of a 400 meters.

23 August 1947, on a wind-aided straight, boardwalk at Long Branch, New Jersey, McKenley was timed in 45.0 for 440 yards, a claimant to being the first person to break the 45 second barrier at 400 meters.

[5] McKenley died at the University Hospital of the West Indies, according to Howard Aris, president of the Jamaica Amateur Athletics Association, who was speaking for the family.
