King's Bridge is a wrought-iron bridge crossing the South Esk River at the mouth of the Cataract Gorge in Launceston, Tasmania.

The bridge span was constructed in Manchester, England and was transported to Launceston for final assembly.

At the time it was named the Cataract or South Esk Bridge and it was the only form of vehicular crossing of that river in Launceston.

In 1904, a second, parallel span was added to widen the bridge.
