The épée (English: or , French pronunciation: ​[epe]), sometimes spelled epee in English, is the largest and heaviest of the three weapons used in the sport of fencing. The modern épée derives from the 19th-century épée de combat, a weapon which itself derives from the French small sword.

As a thrusting weapon, the épée is similar to a foil (contrasted with a sabre, which is designed for slashing). It has a stiffer blade than a foil. It is triangular in cross-section with a V-shaped groove called a fuller. The épée also has a larger bell guard designed to protect the user’s arm. In addition to the larger “bell” guard and blade, the épée weighs more than the foil and sabre which contributes to its reputation of being the slowest form of fencing. The techniques of use differ, as there are no rules regarding priority and right of way. Thus, immediate counterattacks are a common feature of épée fencing. The entire body is a valid target area.
