浮桥，又称舟桥，最早见于中国周朝，是一种简易桥梁，通过联结可浮于水上的物体以临时解决两岸上交通问题，常见于军事用途。先将小船舟用绳子绑起来串联，再用木板平铺于上，便于两岸通行，这就是后来梁桥的雏形。 现在世界上最现代化的浮桥是日本大阪的梦舞大桥。

A pontoon bridge (or ponton bridge), also known as a floating bridge, uses floats or shallow-draft boats to support a continuous deck for pedestrian and vehicle travel. The buoyancy of the supports limits the maximum load they can carry.

Most pontoon bridges are temporary, used in wartime and civil emergencies. Permanent floating bridges are useful for sheltered water-crossings where it is not considered economically feasible to suspend a bridge from anchored piers. Such bridges can require a section that is elevated, or can be raised or removed, to allow waterborne traffic to pass.
