A tractor is a vehicle intended for drawing, towing or pulling some other vehicle or object which cannot propel itself.

The most common use of the word is for a tractor designed for use on farms, typically a simple open vehicle with very large driving wheels and one seat, used for pulling agricultural machinery over rough ground, ploughing, harrowing and similar tasks. Most farm tractors have a means to transfer the engine's power to another machine such as a baler or reaper.

A less-well-used term is used to describe road tractors, which are heavy-duty vehicles with large engines and several axles. These tractors are designed to pull long road trailers, most often for the transport of freight of some kind over a significant distance (See Semi-trailer).

Other forms of tractor include artillery tractors, highly-specialised vehicles used to tow guns of varying weights.
