Fencing at the 2011 Pan American Games – Women's foil

The women's foil competition of the fencing events at the 2011 Pan American Games in Guadalajara, Mexico, was held on October 24 at the Multipurpose Gymnasium. The defending champion was Mariana González from Venezuela.

The foil competition consisted of a qualification round followed by a single-elimination bracket with a bronze medal match between the two semifinal losers. Fencing was done to 15 touches or the completion of three three-minute rounds if neither fencer reached 15 touches by then. At the end of time, the higher-scoring fencer was the winner; a tie resulted in an additional one-minute sudden-death period. This sudden-death period was further modified by the selection of a draw-winner beforehand; if neither fencer scored a touch during the minute, the predetermined draw-winner won the bout.
