A locomotive is a rail transport vehicle that provides the motive power for a train. This list of locomotive builders is ordered by country and includes current and defunct builders. Many of the companies changed names over time; this list attempts to give the most recognisable name, generally the one used for the longest time or during the company's best-known period.
Australia imported its locomotives from the United Kingdom and United States until domestic production began, and even afterwards built many with U.S. and British mechanical equipment.

Historically, major railways in the United Kingdom built the vast majority of their locomotives. Commercial locomotive builders were called upon when requirements exceeded the railway works' capacity, but these orders were generally to the railways' own designs. British commercial builders concentrated on industrial users, small railway systems, and to a large extent the export market. British-built locomotives were exported around the world, especially to the British Empire. With the almost total disappearance of British industrial railways, the shrinking of the export market and much reduced demand from Britain's railways, few British locomotive builders survive.
