The Bauer cabinet, headed by Gustav Bauer of the Social Democratic Party of Germany (SPD), was the second democratically elected government during the Weimar Republic. Bauer's title was minister president until the Weimar Constitution came into force on 14 August 1919, after which he became chancellor of Germany. The cabinet took office on 21 June 1919 when it replaced the Scheidemann cabinet, which had resigned the day before in protest against the terms of the Treaty of Versailles. Although the Weimar Constitution was not in force at the time, the Bauer cabinet is generally counted as the second government of the Weimar Republic.

The Scheidemann cabinet, headed by Minister President Philipp Scheidemann of the Social Democratic Party (SPD), was Germany's first democratically elected national government. It took office on 13 February 1919, three months after the collapse of the German Empire following Germany's defeat in World War I. Although the Weimar Constitution was not in force yet, it is generally counted as the first government of the Weimar Republic.
