The Prussian G 5.5 locomotives were early German freight locomotives with a compound engine. Unlike the otherwise identical G 5.4 they had a leading Adams axle instead of a Krauss-Helmholtz bogie. The delivery of the G 5.5 in 1910 followed directly after that of the G 5.4. A total of either 20 or 25 G 5.5 locomotives were built.

The Deutsche Reichsbahn took over several of these locomotives as Nos. 54 1076-1092; other sources list them as Nos. 54 1080-1082 and 1085-1092. During the Second World War, several more G 5.5's were reclaimed by the Reichsbahn from Poland: Nos. 54 1121, 1141, 1157 and 1185; other sources cite 54 1183, 1217 and 1218.

Other railways also procured this class:

• Grand Duchy of Mecklenburg Friedrich-Franz Railway: Nine locomotives, classed as G 5.4, see Mecklenburg G 5.4.
• Imperial Railways in Alsace-Lorraine: Three locomotives from 1912, see Alsace-Lorraine G 5.5.
