Mathcounts 是美国的一个给6－8年级中学生参加的数学竞赛。从1983年开始，通过学校、地区、州级、国家级四级选拔，评选出一个个人冠军和一个团体（州）冠军。各级竞赛分成三个阶段：Target，Sprint，Team 和 Countdown。

在加拿大的不列颠哥伦比亚省也有类似的竞赛MathChallengers，起始于2004年，规则和 Mathcounts 略有不同。

Mathcounts is a nationwide middle school mathematics competition held in various places in the United States. Its founding sponsors include the CNA Foundation, the National Society of Professional Engineers, and the National Council of Teachers of Mathematics. The competition is designed for sixth, seventh, and eighth graders only.
