The top seven teams at the 2010 Pan American Championship plus hosts Mexico qualified a team for each respective team event, and two athletes for the individual event for that weapon. Also this championship qualified the top 2 athletes per event for the individual event if the country had not qualified through the team event.[1]
Canada has withdrawn from the women's sabre team event, with Panama replacing the country in the event after finishing in ninth place at the 2010 Pan American Championship.[14]
