The Prussian G 12 was a 2-10-0 goods train locomotive with the Prussian state railways (Preußische Staatseisenbahnen).
It was built because it had been shown during the First World War that it was a great disadvantage, from a servicing and maintenance point of view, for each state railway to have its own locomotive classes with no standardization. In addition, the military railways needed a fast, powerful, goods train locomotive, that did not, however, have a high axle load.
