Yobes Ondieki (born February 21, 1961, in Kisii, Nyanza) is a Kenyan former 5000 m runner, who won the World Championships' gold medal in Tokyo 1991.

Ondieki attended Iowa State University, where he captured four Big Eight conference titles, three of them in cross-country.

In 1993, Ondieki became the first athlete to break the 27-minute barrier over 10,000 metres when he ran a world-record time of 26:58.38 at the Bislett Games in Oslo on July 10.

In September 1991, both he and Martin attended the AFL Grand Final and were presented to the crowd as a part of the pre-match entertainment.

The televised footage of Ondieki laughing uncontrollably at the antics of Angry Anderson singing “Bound for Glory” in a blue Batmobile has been used in a more recent advertisement for Carlton Draught.
