Which athlete won the women's 100m hurdles at the 2016 Rio Olympics? Brianna Rollins.

Representing the United States, Brianna Rollins won the final in 12.48 seconds at Rio's Olympic Stadium on 17 August 2016. She led early, cleared the barriers cleanly, and held off compatriot Nia Ali, who took silver in 12.59 seconds.

The result produced a complete American sweep: Kristi Castlin won bronze in 12.61 seconds. It was the first time the United States had swept all three medals in the women's Olympic 100 metres hurdles, and the first sweep by any nation in that Olympic event.

The race also had a notable pre-Olympic twist. Keni Harrison, then one of the world's leading hurdlers, failed to qualify through the U.S. Olympic trials despite setting a world record of 12.20 seconds several weeks later. Dawn Harper-Nelson, the 2012 champion, did not win in Rio. Rollins later competed as Brianna McNeal and was stripped of her 2021 Olympic eligibility after an anti-doping case, but that did not change her 2016 Rio result.
