紧急医疗技术员（英文：Emergency Medical Technician，缩写：EMT）或称救护技术员（英文：Ambulance Technician），通称救护员，通常是指提供紧急医疗服务的专业人员，惟在一些国家，亦会被借用来表示仅提供简单急救服务的人员。

根据美国近年来重要生命之链之观念，在心跳及呼吸停止之状态，人的脑细胞于4分钟开始死亡，于10分钟内脑死成为定局。依据此一观念，全世界目前对病危患者之救治目标在达到4分钟以内有基本救命术（Basic Life Support）之救治；8分钟以内有高级救命术（Advanced Life Support）之救治。

Emergency medical technician (EMT) and ambulance technician are terms used in some countries to denote a health care provider of emergency medical services. EMTs are clinicians, trained to respond quickly to emergency situations regarding medical issues, traumatic injuries and accident scenes. Under the British system and those that are influenced by it, they are referred to as ambulance technicians (often shortened to techs), whereas in the American system and its influenced countries, they are known as emergency medical technicians.
