The German DRG Class 02 (Baureihe 02 or BR 02) engines were standard (Einheitslokomotiven) express train locomotives with the Deutsche Reichsbahn-Gesellschaft.

In procuring a standard express train steam locomotive, the Deutsche Reichsbahn carried out a comparison between a superheated two-cylinder type (the DRG Class 01) and a four-cylinder compound locomotive (the Class 02).

Ten examples of each type were built from 1925, and the Class 02 vehicles were given operating numbers 02 001 – 02 010.

Compared with the Class 01s, these engines had a complicated, and therefore maintenance-intensive, drive; as a result no more were ordered.

From 1937 to 1942 the vehicles were successively converted to two-cylinder simple operation and regrouped as Class 01s with the new numbers 01 011 and 01 233 to 01 241.
