The Olympic record time for the men's 100 metres is 9.63 seconds, set by Usain Bolt at the 2012 London Olympics.
Bolt ran 9.63 in the final at Olympic Stadium on 5 August 2012, defeating fellow Jamaican Yohan Blake and American Justin Gatlin. The performance improved Bolt's own Olympic record of 9.69, set when he won the event at the 2008 Beijing Games.
A common mix-up is Bolt's faster time of 9.58 seconds. That is his personal best and the world record, achieved at the 2009 World Championships in Berlin—not at the Olympics. His 9.63 remains the Olympic record, while his 9.69 from Beijing is the second-fastest Olympic-winning time.
