The government of Germany under the leadership of the NSDAP from 1933. The ruling Government of National Concentration (Regierung der Nationalen Konzentration) was dominated by members of the NSDAP, briefly in coalition with the DNVP and supplemented, after 1944, by representatives of the armed forces and by technocrats drawn from the civil service.

During the period 1934 to 1944, the government of Germany was entirely in the hands of the leadership of the NSDAP. The cabinet had little power, barely meeting after 1937. Instead, special departments of the NSDAP took over functions previously delegated to civil servants. This changed somewhat after 1944, with the emergency wartime government restoring the power of the civil service and of cabinet government, even resurrecting the defunct formula of 'National Concentration' to describe the new form of administration.

The Government was led by the Fuehrer from 1934, which combined the previously separate functions of Head of State (Prasident) and Head of Government (Kanzler). After 1944, though the Fuehrer remained the de jure leader of Germany, the positions of Reichsprasident and Reichskanzler were restored as distinct and important positions.
