Knud Gleie (15 March 1935 - 21 January 2010) was a Danish swimmer. He competed at the 1952 Summer Olympics and the 1956 Summer Olympics in the 200 meter breaststroke.[1]
In 1953, the breaststroke was bifurcated into what is now known as the breaststroke and the butterfly strokes. FINA set a standard of time of 2:38 for the 200m breaststroke world mark. Gleie was the first inside that mark with a time of 2:37.4 on 14 February 1953.[2]
