Vincent Mumo Kiilu (born 3 August 1982) is a former Kenyan sprint runner and hurdler who has competed in the 2008 and the 2012 Olympic Games. He has twice competed at the Commonwealth Games (2006 and 2010), including a relay silver medal on his second appearance. He was selected for Kenya at the World Championships in Athletics in 2003 and 2011. He recently worked as an athletic coach in different capacity, from assistant coach to a head coach.
In the 2012 Olympic 4x400 meter relay semifinal heat, Kiilu cut in front of South Africa's Ofentse Mogawane and both runners fell. Mogawane dislocated his shoulder and was unable to complete the race. The South African team filed an appeal, and the Kenyan team was disqualified when the IAAF ruled that Kiilu had obstructed Mogawane.
Kiilu is affiliated with the Kenyan army and has won medals at the 2003 Military World Games and the 2002 Africa Military Games
