The women's 100 metres hurdles competition at the 2012 Summer Olympics in London, United Kingdom was held at the Olympic Stadium on 6–7 August.

The semi-finals showed all the top athletes were at their best, with the first 5 finalists achieving their personal best, except Sally Pearson who improved the 2012 world leading time.

In the final under London rains, Pearson led from the start but after ticking a hurdle, defending champion Dawn Harper closed fast to make it close. Kellie Wells was solidly in third while Lolo Jones edged Yanit for fourth place. It was an Olympic record for Pearson, a new personal best for Harper and Wells, equal personal best for 6th place Phylicia George and a season best for Jones after a difficult journey from the next to last hurdle four years earlier.
