Richard Kipkemboi Mateelong (born 14 October 1983) is a Kenyan long-distance runner who specializes in the 3000 metre steeplechase. He won an Olympic bronze medal at the 2008 Beijing Olympics and he has two World Championship medals in the discipline.
He was born in Lenape village, near Narok town in 1983. He started running in 1998, while at high school. He graduated from Moi Amalo Secondary School in 2001 and then joined Kenya Police. In 2004 he finished fifth at the Kenyan Olympic trials, missing the Olympics but was selected for the African Championships, where he won a silver medal.
Mainly competing on the European track and field circuit, he qualified for the IAAF World Athletics Final in 2004, 2005 and 2006, eventually winning a silver medal in the latter edition. His times continued to improve and his new personal best of 8:07.50 set in Rome made him the third fastest man that year. The 2007 season marked a breakthrough for Mateelong as he reached the podium at his first World Championships by taking the bronze medal in the men's steeplechase race. He closed the year with a second consecutive silver at the World Athletics Final.
He made a strong start to the 2008 season, becoming African steeplechase champion at the 2008 African Championships in Athletics. He went on to win his first ever Olympic medal at the 2008 Beijing Olympics later that year, finishing behind compatriot Brimin Kipruto and Mahiedine Mekhissi-Benabbad in the Olympic final. He again managed to get in the medals at the 2008 IAAF World Athletics Final and won bronze on that occasion.
The 2009 World Championships in Athletics brought a new steeplechase best of 8:00.89 for Mateelong, and although he did not beat Ezekiel Kemboi it was enough to win his first silver medal at the global championship level. He competed at the 2009 IAAF World Athletics Final (the final edition of the competition) but failed to maintain his form and finished eighth.
At the Doha 2012 Diamond League meeting, Mateelong was second to compatriot Paul Koech in the steeplechase, in a new personal best time of 7:56.81. This makes Mateelong the eighth fastest man in history. He came fourth behind Abel Mutai at the Kenyan Olympic trials, however, meaning he did not gain selection for the Kenyan team.
