At the 2012 Summer Olympics in London, Boubakri qualified for the second time in the women's individual foil event. Unlike her previous Olympics, she excelled through the preliminary rounds by defeating United States' Nicole Ross, and France's Astrid Guyart. Boubakri reached the quarterfinal match of this event, where she was defeated by Italian fencer and three-time Olympic champion Valentina Vezzali, who scored a point during the "sudden death minute" leading to a final score of 7–8.
