Daniel Kipngetich Komen (born 17 May 1976) is a Kenyan middle- and long-distance runner. Remembered for his rivalry with Haile Gebrselassie, his most notable achievements came in a two-year period between 1996 and 1998, during which he broke a string of world records.

Komen currently holds the world record in the 3000 metres with a time of 7:20.67 set in 1996. With his 7.58.61 world best 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. He is also the Kenyan record holder for the 5000 metres both outdoors and indoors.

Komen was the second man, after Saïd Aouita, to break the 31⁄2-minute mark for the 1500 m, the 71⁄2-minute mark for 3000 m, and the 13-minute mark for the 5000 m.
