CCC 加拿大计算机竞赛（Canadian Computing Competition）是加拿大面向全球中学生每年举办一次的计算机程序设计比赛，比赛的目的是为广大中学生提供一个机会来测试自己分析、设计以及编程实现算法的能力。其地位相当于中国的信息技术奥林匹克竞赛。
滑铁卢大学每年2月开始举行CCC竞赛，该竞赛由全世界最大的数学学院Waterloo滑铁卢大学数学与计算机教育中心（CEMC）举办，始于1996年，迄今已有24年历史，累计已有近10万名来自世界各地的中学生参加过该竞赛，国际影响深远广泛。
CCC竞赛具有初级和高级两个级别,级别不同,题目难度不同。每个级别都由五个问题组成，难度从一到五依次递增，每道题15分，总分为75分，答题时间3个小时。比赛题目通常涉及到数学、编程、算法的分析与设计，参赛选手需要具备创造性解决问题的能力以及优秀的编程能力。
一般来说初级组适合任何具有基本编程技能的学生；高级组适合任何具有中级到高级编程技能的学生。参赛学生可根据自己的能力选择适合自己的级别
