按现行国旗采用日期排列的主权国家列表

这是按现行国旗的采用日期排列的主权国家名单。 对于大多数國家来说，国旗采用的日期是明确的，但对于其他國家来说，国旗采用的确切日期不詳或因设计变更而存在争议。 本列表将採用国旗的年份定义为当前国旗连续使用代表一个国家、自治区或被占领国家的年份。仅列出目前的主权国家，尽管旗幟可能是在这些国家获得独立之前就已采用的。 所列国家可能发生了根本性的政权更迭、巨大的地理变化、甚至暂时失去了自治权，或者经历了政治統一或國家分裂。如果该當前國旗在這些事件期间仍在使用，则会列出該旗最初采用的日期。最后一栏列出了旗帜基本设计最後一次的变化（例如比例或色调的变化、紋章或文字的重新设计或星星的添加或删除）当前的國旗设计通常是经过多年的演变（例如美国国旗），也可能是重新采用早期的历史旗帜（例如利比亚国旗）。当前旗帜设计首次使用的年份列在第三栏中。 各国国旗变迁时间轴 The flag has not been in continuous use.
