热身赛是在体育竞赛中，双方为比较对方的实力以及调整选手状况而进行的比赛。与其他一般比赛（包括外围赛)不同的是，热身赛不会影响各参赛队伍的名次。

• 世界杯热身赛(世界杯分组赛进行前各进入决赛周的队伍都进行此赛)通常会与同组对手踢法相近或洲份相同的球队对碰。

An exhibition game (also known as a friendly, a scrimmage, a demonstration, a preseason game, a warmup match, or a preparation match, depending at least in part on the sport) is a sporting event whose prize money and impact on the player's or the team's rankings is either zero or otherwise greatly reduced. In team sports, matches of this type are often used to help coaches and managers select players for the competitive matches of a league season or tournament. If the players usually play in different teams in other leagues, exhibition games offer an opportunity for the players to learn to work with each other. The games can be held between separate teams or between parts of the same team.
