The Prussian Class G 8 locomotives were eight-coupled, superheated, freight locomotives operated by the Prussian state railways. There were two variants: the G 8 built from 1902 with a 14 tonne axle load and the "reinforced G 8" (verstärkte G 8) built from 1913 (later designated the G 8.1) with a 17-tonne (17-long-ton; 19-short-ton) axle load. The latter was the most numerous German state railway (Länderbahn) locomotive, over 5,000 examples being built.
