A lacrosse stick or crosse is used to play the sport of lacrosse. Players use the lacrosse stick to handle the ball and to strike or "check" opposing players' sticks, causing them to drop the ball. The head of a lacrosse stick is roughly triangular in shape and is strung with loose netting that allows the ball to be caught, carried, passed, or shot.

Lacrosse is a contact team sport played with a lacrosse stick and a lacrosse ball. It is the oldest organized sport in North America, with its origins with the indigenous people of North America as early as the 12th century. The game was extensively modified by European colonists, reducing the violence, to create its current collegiate and professional form.
