Yohan Blake (born 26 December 1989), is a Jamaican sprinter of the 100-metre and 200-metre sprint races. He won gold at the 100 m at the 2011 World Championships as the youngest 100 m world champion ever, and a silver medal in the 2012 Olympic Games in London in the 100 m and 200 m races for the Jamaican team.

Blake is the second fastest man ever in both 100 m and 200 m. Together with Tyson Gay, he is the joint second fastest man ever over 100 m with a personal best of 9.69 seconds which he ran on 23 August 2012 with less favorable wind conditions than Gay’s personal best from three years prior.^[4] Only Usain Bolt has run faster.^[5] His personal best for the 200 m (19.26 seconds) is the second fastest time ever after Bolt (19.19 seconds). In this particular race, his reaction time was relatively slow (0.269 s) and had he made even an average start, he could have comfortably set a new world record.^[6] He holds the Jamaican national juniorrecord for the 100 metres, and was formerly the youngest sprinter to have broken the 10-second barrier (at 19 years, 196 days).
