室内袋棍球（Box lacrosse 或 indoor lacrosse），是袋棍球运动的室内版本，主要流行于北美洲。该项运动起源于加拿大，在那里已经比传统的草地袋棍球更受到欢迎。比赛由两支球队各6位选手上场，一般直接使用冰上曲棍球的场地，只是未覆盖冰而已。相对于草地袋棍球的室外开放性空间，此种室内封闭性场地常被称为「盒子」。比赛的目的是使用一支手持的长袋棍来接球、运球及传球，并尽可能将硬橡胶球猛投进入对方的球门。

当今世界最高水准的室内袋棍球竞赛是加拿大袋棍球协会的高级A组（不列顚哥伦比亚袋棍球协会的西部袋棍球协会与安大略袋棍球协会的袋棍球主系列），以及美国的国家袋棍球联盟（NLL）。

Box lacrosse, also known as indoor lacrosse and sometimes shortened to boxla or simply box, is an indoor version of lacrosse played mostly in North America. The game originated in Canada, where it is the most popular version of the game played in contrast to the traditional field lacrosse game. It is played between two teams of six players each, and is traditionally played on an ice hockey rink once the ice has been removed or covered. The playing area is called a box, in contrast to the open playing field of field lacrosse. The object of the game is to use a long handled racket, known as a lacrosse stick, to catch, carry, and pass the ball in an effort to score by ultimately hurling a solid rubber lacrosse ball into an opponent's goal.
