Daniel Kipngetich Komen (born May 17, 1976) is a Kenyan middle- and long-distance runner.
Remembered for his rivalry with Haile Gebrselassie, Komen’s most notable achievements came in a two-year period between 1996 and 1998, during which he broke a string of world records.
He currently holds the world record for the 3000 metres both outdoors (7:20.67 set in 1996) and indoors (7:24.90 set in 1998). In addition, with his 7.58.61 world record in the 2-mile race set in 1997, he remains the only man in history to run back-to-back sub-four-minute miles, splitting circa 3:59.4 on both the first and second half of the race.
Komen was also the second man, after Saïd Aouita, to break both the 13-minute mark for the 5,000 m, the 7½-minute mark for 3,000 m, and the 3½-minute mark for the 1,500 m.
