装甲列车（Armoured train）是一种武装化的火车，在****又称「铁甲列车」。利用火车的高载重力可以轻易加挂大量火砲和装甲，有陆地战舰之称，但缺点是移动范围受限于铁路，战术运用上较难，铁路万一被破坏也就无用武之地。

装甲列车在20世纪早期至二战期间较风行，最初是将多辆战车固定放于火车拖板上开砲，后来发现其战术潜力，逐渐开始专门建造。

装备最多的国家为苏联，第二为波兰，较便于防守陆地为主的国家。二战后战斗机和飞弹的发展使庞大的装甲列车优势逐渐丧失，逐渐消失于军事领域，但俄罗斯和传闻若干国家依然有搭载弹道飞弹的机动发射列车在使用中，该种发射车也装有一些轻武器和装甲，可以看作装甲列车的一种。主要价值在于可以机动化高重量的弹道飞弹并可藏于隧道中，随时就地可以发射作为一种核威摄力量，好比陆地的核子潜舰。

An armoured train is a railway train protected with armour. Armoured trains usually include railroad cars armed with artillery and machine guns. They were mostly used during the late 19th and early 20th century, when they offered an innovative way to quickly move large amounts of firepower. Most countries discontinued their use - road vehicles became much more powerful and offered more flexibility, and train tracks proved too vulnerable to sabotage as well as to attacks from the air. However, the Russian Federation used improvised armored trains in the Second Chechen War of 1999-2009.
