袋棍球（Lacrosse），又译长曲棍球、曲棍网球、棍网球、兜网球、袋球或网棒球，是一种使用顶端具有网状袋子的长棍作为持球工具的团队球类运动。起源于北美印第安人部落，原本不限人数，最多可达双方各一千余人。移民至此的法国人发现后，加以改良并制订规则，因而形成今日的状态。

得分的形式是把圆球射进对手的龙门内，胜利归于入球较多一方，而比赛时，球员要求用棍子来传、接和运球。防守以阻止对手射门及让对手所持的球从棍的网子内跌出来为主，守卫容许用手持的棍来击打对方，身体的碰撞，或者站在恰当的位置，来进行合法的防御。

Lacrosse is a contact team sport played between two teams using a small rubber ball (62.8–64.77 mm (2.472–2.550 in), 140–147 g (4.9–5.2 oz)) and a long-handled stick called a crosse or lacrosse stick. It is often considered as a rough sport, with slashes and intense checks to the stick and body. The head of the lacrosse stick is strung with loose mesh designed to catch and hold the lacrosse ball. Offensively, the objective of the game is to score by shooting the ball into an opponent's goal past the goalie, using the lacrosse stick to catch, cradle, and pass the ball to do so. Defensively, the objective is to keep the other team from scoring and to gain the ball through the use of stick checking and body contact or positioning. The sport has four major types: men's field lacrosse, women's lacrosse, box lacrosse and intercrosse. The sport consists of four positions: midfield, attack, defense and goalie. In field lacrosse, attackmen are solely offensive players (except on the "ride", when the opposition tries to bring the ball upfield and attackmen must stop them), defensemen or defenders are solely defensive players (except when bringing up the ball, which is called a "clear"), the goalie is the last line of defense, directly defending the goal, and midfielders or "middies" can go anywhere on the field and play offense and defense, although in higher levels of lacrosse there are specialized offensive and defensive middies. Long stick middies only play defense and come off on the field on offense.
