The women's 100 metres hurdles at the 2008 Summer Olympics took place on 17–19 August at the Beijing National Stadium.

In the semi-final, Jones separated from the field by .19, setting a wind legal personal best 12.43 and a new fastest time of the year.

By the fourth hurdle she had almost a full stride lead over the wall of competitors across the track behind her, with Jones starting to gain a slight advantage.

Jones continued to pull away to a full stride on Harper as McLellan fell back to run even with the wall.

Behind her, McLellan, Priscilla Lopes-Schliep, Damu Cherry, Delloreen Ennis-London and Brigitte Foster-Hylton (the wall) hit the line together.
