A paddle is a tool, originally a propulsion implement for mixing or pushing against liquids, typically in order to propel a boat. Paddles for use in canoes consist of a wooden, fibreglass or metal rod (the shaft) with a handle on one end and a rigid sheet (the blade) on the other end. Paddles for use in kayaks are longer, with a blade on each end, and usually no handles.

The paddle is held with two hands, some distance apart from each other. For normal use, it is drawn through the water in a backwards direction. The two blades of a kayak paddle are dipped alternately on either side of the kayak. A paddle is distinguished from an oar in that the paddle is held in the user's hands and completely supported by the paddler, whereas an oar is primarily supported by the boat. Because the kayak paddle is not supported by the boat, paddles made of lighter materials are desired, it is not uncommon for a kayak paddle to be two pounds (32 ounces) or less in weight.

On mechanical paddle steamers, the motorized paddling is not done with a mass of paddles or oars but by rotating one or a few paddle wheels (rather the inverse of a water mill)
