中场（Midfielder）是足球中一个重要位置，主要在球场中间活动，负责连系前锋与后卫，就如右方图中蓝色位置。他们的主要功能是保持足球控制权在己方、向对手作出拦截争夺皮球、制造攻势，以至入球。一些中场球员是担任防守性较强的位置，一些中场球员是担任较前位置为前锋创造机会。一场球赛中，中场球员的数量并不固定，通常视乎球队需要及球员特性而安排。

出色的中场球员需要很高的技术及体能，以应付任何球赛中的拦截、带球、射门、调动及传球。

A midfielder is an association football position. Midfielders are generally positioned on the field between their team's defenders and forwards. Some midfielders play a more defensive role, breaking up attacks and are more disciplined to their roles they are otherwise known as defensive midfielders, while others blur the boundaries, more mobile, efficient in passing and are commonly as deeplying playmakers, box to box or holding midfielders. The number of midfielders on the team and their assigned roles depends on the team's formation; the collective group of these players on the field is sometimes referred to as the midfield.
