紧急地震速报(Earthquake Early Warning)是日本气象厅(Japan Meteorological Agency)于2004年开始试运行，2007年正式投入使用的地震预警系统。系统利用了P波和S波的速度差，以及地震波和电磁波的速度差对地震进行快速预警。紧急[[地震]]速报是世界范围内，第一个投入使用、台站密度最高、台站数量最多、覆盖范围最大、耗资最多、性能最好的地震预警系统。系统的[[吉祥]]物是日本神话中导致大地震动的鲶鱼。紧急地震速报是日本的重要之物，在日本生产的手机，不安装紧急地震速报接收器不允许出厂。电视台全部配备紧急地震速报，紧急地震速报发布时，会有短信息、广播等报告。
