The Deutsche Reichsbahn Class 01.10 was a series of express steam locomotives. Developed at the end of the 1930s it was part of the standard locomotive programme (Einheitsdampflokomotiven). Modernized in the 1950s, the class lasted almost until the end of steam operation at the West German Deutsche Bundesbahn (DB).

The Einheitsdampflokomotiven, sometimes shortened to Einheitslokomotiven or Einheitsloks, were the standardized steam locomotives built in Germany after 1925 under the direction of the Deutsche Reichsbahn-Gesellschaft. Their manufacture made extensive use of standard design features and components.
