装甲架桥车(armoured vehicle-launched bridge - AVLB) ，指装有车桥及其架设、撤收设备的装甲车辆，主要用于快速架设桥梁，令部队迅速通过河流，普遍装备于工兵部队。装甲架桥车可由一般坦克或自走炮底盘改装而成，部份会保留机枪作防卫用途。

An armoured vehicle-launched bridge (AVLB) is a combat support vehicle, sometimes regarded as a subtype of Military engineering vehicle, designed to assist militaries in rapidly deploying tanks and other armoured fighting vehicles across gap-type obstacles, such as (and primarily) rivers. The AVLB is usually a tracked vehicle converted from a tank chassis to carry a folding metal bridge instead of weapons. The AVLB's job is to allow armoured or infantry units to cross craters, anti-tank ditches, blown bridges, railroad cuts, canals, rivers and ravines), when a river too deep for vehicles to wade through is reached, and no bridge is conveniently located (or sufficiently sturdy, a substantial concern when moving 60-ton tanks).
