A paddle steamer, or paddle wheeler, is a type of boat that is driven forward by a large wheel. Usually the wheel is at the back of the paddle steamer (stern-wheeler), but there can also be a wheel on either side (side-wheeler).

Paddle steamers are usually found on still, calm water like rivers. The paddle wheel can be driven by either a steam engine or a more modern electric or diesel engine.
