Kenenisa Bekele Beyecha (Oromo: Qananiisaa baqqalaa; Amharic: ቀነኒሳ በቀለ; born 13 June 1982) is an Ethiopian long-distance runner. He was the world record holder in both the 5,000-metre and 10,000-metre from 2004 until 2020. He won the gold medal in both the 5,000 m and 10,000 m events at the 2008 Beijing Olympics. At the 2004 Olympics, he won the gold medal in the 10,000 m and the silver medal in the 5,000 m.
He is the most successful runner in the history of the IAAF World Cross Country Championships, with six long (12 km) course and five short (4 km) course titles. He won the 10,000 m title at the World Championships in Athletics in 2003, 2005, 2007 and 2009 (matching Haile Gebrselassie's four in a row win streak). Kenenisa was unbeaten over 10,000 m from his debut in 2003 until 2011, when he failed to finish at the World Championships final.
At the 2009 World Championships in Athletics he became the first man to win both 5000 m and 10,000 m title at the same championships. Over 5000 m he has also won an Olympic silver (2004), World Championship bronze (2003), two African Championship titles and one All-Africa Games gold medal. He also won the 3000 metres title at the 2006 World Indoor Championships.
On 6 April 2014, he produced the sixth fastest marathon debut ever on a record-eligible course with his victory at the Paris Marathon, in a course record time of 2:05:04. On 25 September 2016, Kenenisa won the Berlin Marathon in a time of 2:03:03, a new personal best, then the third-fastest marathon of all time. On 29 September 2019, he again won the Berlin Marathon in a time of 2:01:41, two seconds slower than the then world record of 2:01:39 set by Eliud Kipchoge in the 2018 Berlin Marathon. Considering his accomplishments in cross country, track, and road racing, many consider him to be the greatest distance runner of all time.
