Khalid Khannouchi (Arabic: خالد خنّوشي) (born September 12, 1971) is a Moroccan-born American retired long-distance runner.

He is one of only five men to break the marathon world record more than once, and one of only five to break their own marathon world record (the others are Jim Peters, Derek Clayton, Eliud Kipchoge, and Haile Gebrselassie).

Khalid fell out with the Moroccan athletics federation over training expenses and moved to Brooklyn, New York City in 1992 with three of his friends.

He first gained broad notoriety by winning the 1997 Chicago Marathon by over a minute with a time of 2:07.10, breaking the 12-year old course record held by Steve Jones.

Khannouchi officially retired on March 27, 2012 due to recurring foot injuries since 2003.
